Thoughts On Sunlight

We live in a world where everything is powered by something. Our technology is fueled by electricity. Our cars are fueled by fossil fuel (although hopefully not for much longer). Our generators are fueled by everything from coal to running water to the splitting of atoms. We are fueled by food, which we break down to release energy.

But at the core of it all, the world is fueled by one main energy source: sunlight.

Let us retrace the steps.

The device you are using to read this is charged by electricity provided by a power generator. Whatever the source of electricity is, humans are required to power the machines and we are fueled by food. The food we eat are either plants, or meat from animals that consume plants. Plants generate their energy through photosynthesis, where sunlight is used to store energy in carbohydrates. 

Ergo, sunlight fuels us all – we are all made of and held together by sunlight.

The Sun is positioned 152 million kilometres from Earth. This means that sunlight travels 152 million kilometres – a distance that takes even light eight minutes to traverse – to feed Earth, brighten our days and make us feel warm and fuzzy. 

Sunlight also heats the earth and seas to power various weather cycles and currents, provides heat to keep life possible and most importantly, lets us see because it floods our day with photons. 

Just something to think about the next time we enjoy a delightful nap in a warm, cozy sunbeam.

Cakelet

If you are feeling lazy but want a decent, filling, wholesome breakfast or brunch, try making a cakelet – a cross between a pancake and an omelet. By combining the two, the recipe becomes surprisingly easier, resulting in a savoury, fluffy, tasty meal.

Ingredients:
2 large eggs
2 tablespoon plain flour
1/4 teaspoon baking powder
1/4 cup grated cheese
1 tablespoon butter
Pinch of salt

  1. Whisk the eggs until they are completely combined with no whites floating around
  2. Add the flour, baking powder, cheese and salt to the egg and whisk it lightly altogether
  3. Melt the butter in a small skillet (about 8″ in diameter) at medium heat
  4. Pour in the batter
  5. Once you see tiny bubbles starting to form and the mix starts to firm, flip the cakelet like a pancake
  6. Cook the other side for 2 minutes, until both sides are golden and it springs back when you poke the top
  7. Serve it any way you want it: the cakelet goes well with either sweet toppings such as jam or relish, or savoury toppings such as hummus, roasted tomatoes or bacon

If you find that the cakelet is too heavy, feel free to cut back on the amount of butter and cheese used. It is a very forgiving recipe that can be whipped up with little ingredients and minimal preparation, unlike a pancake or an omelet.

Avocado Pasta

Pasta with homemade sauce is one of the best meals to cook at home, because it is often easy, makes a large portion and tastes delicious despite its simple recipe. It is also easily adaptable, such as this avocado pasta recipe which is an alternative to pesto, if avocados are in season and cheap.

When cooking pasta, remember to heavily salt the water (“as salty as the Adriatic Sea” as Italians might say) for extra flavourful pasta and to save 1-2 cups of pasta water for additional starchiness to the sauce.

Ingredients (serves 4):
2 avocados
2 cloves garlic
1/2 cup basil
2 tablespoons lemon juice
1/3 cup olive oil
1 cup cherry tomatoes
100-150g bacon/pancetta/chicken (optional)
350-400g pasta (any, but recommend fusilli or penne)

  1. Cook pasta to preference (suggest 12-13 minutes in salted boiling water)
  2. Chop avocados into medium-sized chunks to make it easy to process
  3. Add avocados, peeled garlic, basil and lemon juice to the food processor
  4. Season with salt and pepper to taste
  5. Start blending all of the ingredients in the food processor and add olive oil in a slow stream (or intermittently and pulse)
  6. Blend until all ingredients have fully emulsified with no pools of oil
  7. Cut cherry tomatoes in half
  8. If using bacon or pancetta, pan fry until lightly crisp
  9. Tomatoes can be cooked in the bacon/pancetta oil if you prefer
  10. If using chicken, cut into strips or cubes, season with salt and pepper, then pan fry until fully cooked
  11. Combine pasta, avocado sauce, cherry tomatoes, meat and splash of pasta water (avoid making the mix too liquid)
  12. Garnish with basil leaves and serve

Sausage Stew

This is a recipe for a simple, but hearty and delicious sausage stew. Because of its short ingredient list and the fact that you can store most of the ingredients for a long time (canned or frozen), it makes for an ideal back-up meal option. Furthermore, the amount of each ingredient can be varied quite a bit and substituted depending on your preference. It is also quick to make.

All in all, it is an ideal recipe if you are learning how to cook.

Ingredients (serves 3-4):
6 fresh sausages (ideally chorizo or pork & fennel, but any uncooked fresh ones will do)
400g canned chickpeas
400g canned crushed tomatoes
3-4 mushrooms (button or Swiss)
0.5-1 bag of spinach
Italian spices (suggest any mix of smoked paprika, oregano, rosemary, thyme)
Grated cheese (optional)

  1. Peel the sausages and dice or tear the meat into very small pieces
  2. Heat pan (preferably a deep one like a wok or broad pot) to medium-high and start cooking the sausages
  3. Break up the sausage meat as it cooks with a spatula or wooden spoon
  4. When the sausages are browning, add thickly sliced mushrooms and cook for 2 minutes
  5. Add smoked paprika and spinach, then toss for just under a minute to let the spinach wilt slightly
  6. Add canned chickpeas, tomatoes and rest of the spices
  7. Mix everything together and cook until liquids start to bubble
  8. Turn heat down to low and simmer the stew, add in rest of spices, season with salt and pepper
  9. Mix in handful of grated cheese and let it melt in as the stew simmers
  10. Serve

Other than the sausages, chickpeas and tomatoes, almost every other ingredient is optional. You can take the cheese, mushrooms and spinach out, and add other vegetables you would like, such as onions or capsicums. If the stew is too meaty, you can reduce the number of sausages to 3-4 instead.

You can even take the chickpeas out and instead crack two or three eggs into the stew when it is simmering, then bake for 7-10 minutes in the oven to make baked eggs.

Proust Effect

In his novel In Search of Lost Time, French writer Marcel Proust explored the power of smell in invoking memories. He tells a story of how he would have tea-soaked madeleine to trigger memories from his childhood. Proust called these memories involuntary memories, because it is not recalled on purpose, but automatically triggered by a sensory stimulus such as smell.

Our brain processes memory in a strange, abstract way. Because it doesn’t record memories like a photograph or video, memories become unreliable the older they are. We have very limited memories of our childhood, unless they are paired with specific emotions or memorable events.

Smell triggers involuntary memories because the part of the brain that senses smell, the olfactory bulb, lies right next to the hippocampus and amygdala. These sections of the brain handle memory and emotion respectively, so there is a theory that we form memories linked to different smells, especially if it is an emotional one. There is also some research to suggest a phenomenon called reminiscence bump, where we have a tendency to recall more triggered memories from adolescence and early adulthood. This may be because these are the years when we form our self-identity.

This may be why smells of certain dishes or baking may act as powerful mediums to recall treasured childhood memories, such as the love we received from our parents. Even as adults, we all have specific dishes that we crave to comfort us when we are feeling stressed or lonely. More often than not, these dishes will have a story behind them, whether you remember it consciously or not. When we smell the dish being prepared, we become drowned in nostalgia. The emotions of happiness, safety and love linked to these memories distract us from the pains of life for just long enough that we can have the strength to make it through another day.

Proust talked about a tea-soaked madeleine being his key to his memories. What food is the proverbial madeleine to you?

The Importance Of Television

Fire is considered one of the most important discoveries in the history of our species. Since the dawn of time, it has provided us with warmth, light, cooked food and the power to invent even more things.

We can see how important fire was to our ancestors from how integral it was within a house.
In prehistoric times, there would always be a fire at the centre of a cave or hut, where the family could gather around for warmth and light. Here, they would warm themselves on a cold winter’s day and cook meat that they hunted during the day to tenderise it.

Unlike the old days, we no longer have open fires in the house. Instead, fire has been split into three different forms.

  • Instead of huddling around an open fire for warmth, we have boilers and hot water cylinders to warm our houses.
  • Instead of cooking our food over a campfire, we have gas or electric stoves and ovens.
  • Instead of the flickering flames providing us with light and distraction, we have television and computers.

Of course, we still have fireplaces, barbeques and candles, but the modern person tends to rely more on modernised versions of fire.

An interesting takeaway from this theory is how television is the modern form of the psychological comfort that fire provided us. In prehistoric times, people would struggle to stay alive, running from predators and hunting to feed the family. Looking at the fire mindlessly at the end of a hard day’s work would have been a way to destress and unwind.

Nowadays, most of us are lucky enough to not have to fear death on a day-to-day basis, but we still suffer constant stress from the busy modern life. Perhaps sitting in front of a television or computer to procrastinate for half an hour is not the worst thing in the world.

That said, everything should be done in moderation. It is good to relax for a set amount of time, but if you spent every evening after work staring at a screen without an original thought, your mind will dull and atrophy.

So, it is good to balance out the mindless entertainment such as comedy or reality shows with films that provoke thoughts and emotions, documentaries that provide you with knowledge, and shows that stimulate your creativity.

Most importantly, what you think and feel and learn after watching these should act as fodder for conversations that help deepen your connection with other people.

Time Divided

Even though time is continuous, we like to think of think of time in segments.

The most basic unit is the year. Every time the Earth rotates once around the Sun, we take stock of the year gone by, while setting resolutions for the next year. Technically, whether it is 300 or 400 days, time has passed, yet we always mark changes by the number of years. For example, we use age as a marker of what stage of life we should be at (even if it is not a very accurate marker).

Another classic example is the four seasons. The making of accurate calendars and units of time was critical in the development of agriculture as it allowed us to plant many different crops with high efficiency and yield. In older times, people may have marked time by reminiscing what happened around the time of the last harvest while eating food made with ingredients harvested at that time.

Some segments are less regular, such as the last time you caught up with someone, or whenever you have a big life change such as moving cities. Some people may mark the chapters of life by the person they were dating at the time, or the stage of professional development, such as what year of university they were in.

Why do we obsessively divide time and remember our lives in artificial, bite-sized chunks? Our brains are very good at noticing patterns and change, but not so good when the changes are gradual and continuous (change blindness). Ergo, dividing up time into segments help us process the past.

It is hard to notice how much someone’s hair has grown if you see them every day. It is hard to notice how different you and your partner have become with time until a conflict arises. It is hard to notice how much we have grown and matured and changed without consciously reflecting from time to time.

Another interesting thing to consider is that what you use as a marker of time may suggest what you are prioritising. When you look back, what is the unit of time you use to divide your life? Is it the last time you moved cities? Your last boyfriend or girlfriend? Your last big trip? A moment where you came to an epiphany?

Whatever it is, it is a useful practice to periodically look back on all the segments that make up your life, such as by keeping a journal and reading it later. This will let you be more aware of how you are developing as a person and help you steer yourself in the general direction that you want your life to take you. At the very least, it is amusing to notice the subtle differences between the past and the present you.

Salt And Flavour

A well-known cooking fact is that salt “brings out the flavour” of foods. This not only applies to meats and vegetables, but also unlikely foods and drinks such as brownies, watermelons, coffee and chocolate milk.

Salt (sodium chloride) will dissolve in water to form sodium and chloride ions. Sodium ions interfere with the way your taste buds sense flavour, suppressing bitterness. This is why adding a dash of salt to coffee and chocolate milk will make it taste fuller and smoother.

Furthermore, the sodium ions enhance flavour by making taste buds more sensitive for other flavours such as sweet, sour and umami (savoury). Lastly, in the case of chocolate milk, the slight salty taste gives a greater contrast for the sweet flavour, making the drink taste slightly sweeter.

Tea Etiquette

The following are some etiquettes invented in Victorian England when the culture of tea drinking boomed:

  • Stir the tea with your spoon back and forth rather than swirling it
  • The spoon is placed behind the cup and never left in the cup
  • Hold the teacup by its handle between your thumb and fingers without curling your fingers in the hole
  • Holding out the little finger is not a traditional way of holding a teacup and can be considered rude
  • Never cradle the cup with your fingers, keep the saucer close to the cup instead
  • Sip instead of slurping
  • Never sip tea from the teaspoon
  • When drinking the tea, look into the teacup, never over it
  • When not drinking the tea, the cup should be placed on the saucer

The “pinky out” rule of fanciness likely came from a Roman tradition of a cultured person eating with three fingers, contrasting the commoner using five. It is likely that the “pinky out” rule is a misinterpretation of the “three finger” rule and a misguided show of elitism (or irony).

Of course, these “etiquettes” are merely arbitrary social rules imposed on what can be enjoyed however you like it, so unless you feel extra fancy, drink tea in whatever way you please.

Chocolate Overdose

It is common knowledge that you should not feed dogs and cats chocolate as it is poisonous to them. This is because chocolate contains a substance called theobromine. The name theobromine comes from the Greek words theo (“god”) and broma (“food”), thus meaning “food of the gods”.

Cats and dogs metabolise this chemical very slowly, so they can easily overdose on it. Theobromine poisoning causes vomiting and diarrhoea initially, then progresses to cause hyperactivity, cardiac arrhythmias (irregular heartbeats), seizures, internal bleeding, cardiac arrest, respiratory failure and eventually death. Although cats and dogs have the same metabolism rate of theobromine, there are far less cases of cats overdosing on it as they do not have sweet taste receptors and do not particularly like the taste of chocolate.

Luckily for us, the human body can metabolise theobromine much more efficiently and we are much less likely to get theobromine poisoning (although it is still possible if you eat too much of it). Although it is weaker, theobromine behaves similarly to caffeine in the human body. It stimulates the heart to beat faster, relaxes the blood vessels, reduces blood pressure and stimulates your nervous system to decrease your tiredness and give you a “buzz”.

The effects are potent enough that there is some evidence that eating dark chocolate (which has a higher theobromine content) regularly can reduce your risk of heart disease. However, this is counterbalanced by the negative health effects of sugar and fat found in chocolate. That being said, a small amount of chocolate every now and then not only has a positive effect on your heart, but is a great medicine for your exhausted mind and soul.
