Cooking is Chemistry – A Great Way to Know Your Food

And its a lot more socially acceptable than most other amateur endeavors in chemistry..

I credit two things for my ability to cook.  First is my mom, who not only shared a wealth of Korean cooking methods, but also took specific effort to learn more common American meals so that she could integrate her knowledge.  Most of my cooking knowledge comes directly from her, but I can’t exactly help you learn more by suggesting you find a mom or dad who is great at cooking.  😉  If you are lucky enough to have a parent around who cooks well, be sure to take some time and spend it with them in the kitchen!  There’s a reason these traditions are worth carrying on – and that is that they taste delicious!  Oh yeah, there are probably some great emotional and sentimental reasons in there too, but I’m trying to stick to the food and the chemistry today.

The second great influence on my cooking is the few chemistry classes I’ve taken throughout the years, up to an undergraduate level.  Because really, when you break it down, the things you do in the kitchen aren’t all that different than what one might do in a chemistry lab.  Heat some liquid, stir some reagents, the ingredients themselves may not be identical but they do share some important characteristics.

For example, acids and bases mix to create water and salt. So if you’re adding acidic and basic ingredients to the same dish, extra salt might be just too much!

And speaking of salt, the reason why you add a pinch to a pot of water before boiling it is that because the extra ions of Na and Cl will allow the water to reach a higher heat before boiling.  So not only is the boiling point of water dependent on atmospheric temperature, its also a function of how many electrolytes are dissolved in the liquid!

Of course, oil and water don’t mix too well  – but they can both attach to fiberous plant pieces and create a consistent paste or thick soup.  Now remember, the smaller you cut up your veggies the more surface area they have.  And surface area is the primary factor in how many bonds a particular number of atoms can forge.

In fact, most organic compounds will partially dissolve in either water or oil (or both!) so we use oil to liquefy eggs (mayonaise) and we use water to extract delicious from coffee beans and tea leaves.  If something doesn’t want to dissolve in either of those and you insist on liquefying it, be sure to remember alcohol and acids like vinegar are needed.

And obviously, we can’t forget the chemistry of gluten that is at once desired for its ability to trap oxygen and rise to a fluffy bread and simultaneously reviled by those of us with an incompatible immune system.

Whether its the way heat transfers or how starches can be converted to sugar in the right heating conditions, there are a million little lessons we can learn from applying classroom chemistry to the household kitchen.  There are of course, other ways you can apply chemistry as a hobby.  But most of those involve explosions and toxic solvents that are kind of frowned upon in this age of security and paranoia!

Stir Fry – Intro 101

So you want some stir fried vegetables but you don’t know what ingredients to start with? Maybe you got the veggies in mind, but end up with some dried out husks or a mushy paste? Read on brave souls, I’ll share the secrets of stir fry that I’ve learned this Christmas.

The first essential step is to pick what you’re working with. Generally, you’ll want a good bit of onions, some bell peppers (green and red if possible), some long green onions (aka scallion), some cracked black pepper, some garlic, and sesame oil.

That part is pretty much essential, but you can branch out further with squash, zucchini, peas, carrots, spinach, or anything you care for, really.

The trick is to keep the veggies most with the sesame oil and to cook them quickly at a high heat.

The other trick is the chronological order ingredients are added to the skillet. Vegetables should be added from those with the highest wetness, thickness, and density to those with the least.

This means you’ll probably start off with peas and carrots or peppers and onions in the pan, and you’ll add the scallion in last. When all the ingredients are equally mixed with the sesame seed oil, some cracked black pepper will really activate the flavors and give your stir fry a kick.

With just the various onions and peppers, this stir fry mix will complement any type of meats and rice. In future posts, I’ll try to add some popular variations of the stir fry basics, so stay tuned!

Gluten Free Meal-Burger

The hamburger is an American classic, and properly loaded up it can provide just about all the essential nutrients in a convenient starchy bun. Unless you can’t eat the bread that is.

Of course, everyone loves some fried potatoes with their burger, but I was kind of in a rush the other day and needed to turn a half pound of beef into a whole meal-burger. Luckily, there were plenty of fresh veggies around…

  • 1/2 pound beef
  • 2oz. mozorella cheese
  • 1/6 large onion
  • 2 stalks long green onion
  • 1 slice red pepper
  • About 10 leafs of spinach
  • 1 slice back bacon

Shape the burger into a patty, just be sure not to overhandle it or add salt before it cooks.  Drop the burger and the back bacon into a frying pan at about half heat, flipping the rasher (bacon) quickly and resting it on top of the burger.  (I started off with low-fat beef so I had to make sure to conserve oils)

When the bacon is ready, chop up all the veggies and add them to the frying pan.  Add peppers & onions first, then the spinach & long green onions.

As the veggies start to fry, flip the burger and add the first layer of cheese to the top.  Place the bacon off to the side for a second then start to pile up the hot veggies onto the cheese.  Once the veggies start to melt the cheese pretty well, add another layer of cheese an top of the veggies and drop the bacon on top of that!

Not only does the gluten-free meal-burger fill you up like a complete meal, it tastes pretty great as well!  Since mine was a bit dry, I made up a quick sauce from spicy brown mustard and some regular old fashioned mayo.  If you started with a fattier ground beef, you might not even need that!

Happy holidays and happy eating!
