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!

Eat Well, Eat Cheap

Here’s an example of what I got on my last trip to the grocery store. Just because you can’t eat gluten and don’t have much money to spend on food doesn’t mean you can’t still enjoy healthy and delicious meals:

3/4 lb lean steak – $3.50
1 lb 93/7 ground beef – $3
1 lb asparagus – $2.50
2 lb broccoli – $3.25
2 boxes Chex – $6.30
1.5 lb muscadines – $4
1 gallon milk – $2.50
8 oz mozorella – $2

That’s about $6.50 for meat, $6.50 for green veggies, and $6.50 for grains. Dairy and fruits are about $4 each.

This will last me a week in addition to some things that are left over. Eggs, coffee, sugar, butter, all those basics are pretty cheap and don’t have to be purchased every week.

Just make sure you’re stocked up on pepper, salt, garlic powder, and some basic herbs like oregano, thyme, and rosemary. From there, you can make a lot of delicious meals in no time, for low cost!

Right now, I’m sitting around, waiting for a few of those thin-sliced lean steaks to sear up a little bit. There’s also about a half pound of brocolli steaming next to it. Despite the steak and eggs I had for breakfast, and the multiple bowls of cereal in between, my body is ready for the next round of healthy foods and my energy levels are staying high.

Now, if I could just get a little more disciplined with exercise, I might actually resemble a healthy person! For all the years I ate gluten unknowingly, I never would have dreamed that I could feel this good again. Healthy food and a bit of physical activity just makes it even better.

Saved by the Potato

Prices are going up, everywhere.  If you’ve been to a gas station or a grocery store in the last few years, you know exactly what I’m talking about.  However, the guys at the federal budget office apparently don’t go to these places because they say inflation has been kept moderate at about a 2% rate.

Of course, when you manipulate the numbers like they do, its easy to see how they come to such an out of touch conclusion.

The government argues that food prices only rise at about 4% a year, but this is only true if the people substitute fresher, healthier, more expensive foods with cheaper ones.  According to the CPI, food is only slightly more expensive but what you’re eating isn’t as good as it used to be.  Here are some examples comparing the 1970s to now:

  • Fruit:  In the 1970s, the average person ate about 22 pounds of fresh fruit in a year.  Since the price of fruit is skyrocketing, you only get 4 pounds a year today – and you pay way more for way less.
  • Beef:  You can eat the same amount of beef today that you did in the 1970s, but it will cost a bit more.  Of course, the standard for beef in the 1970s was lean steak and today its high-fat ground beef patties.
  • Fresh vegetables:  Fresh vegetables have risen 20% in the last two years.  So CPI assumes that you will eat less vegetables.  What’s it replaced with?   Sodas, cookies, cakes, and candies actually dropped in price, so they expect we’ll have more of that.

Now, for someone eating gluten-free on a budget, this is quite the conundrum!  Processed foods are essentially off-limits and fresh foods are becoming more expensive by the day.

This brings me to the title of my post, “Saved by the Potato”

  • They’re cheap
  • They’re naturally gluten-free
  • They’re healthy
  • There are literally hundreds of ways to cook them, season them, and serve them
  • The high plant-starch seems a good replacement for wheat and helps promote a balanced diet

Don’t get me wrong, potato prices are going up too.  Unfortunately though, its only candy and baked goods that are dropping in price, and that won’t help you if you’re going gluten-free.

Will Power isn’t Infinite

So, I was really missing pizza.  It had been about two years since I had a decent slice, and I just couldn’t take it.  After we got back from Christmas vacation I gave in and ordered a super-supreme pan pizza.  It wasn’t gluten-free, it was a temporary pleasure followed by the last two weeks of pain, exhaustion, and confusion.  The bad news is, I didn’t manage to get pictures of my gluten-free fried chicken for the website, yet.  I’ve also missed a lot of work and fallen behind on my publishing goals 🙁

I think I learned a lesson and I think I’ve put the pizza craving to rest.  The taste of wheat can be great, but it literally lasts a few minutes compared to what could be days or even weeks of suffering.  I should have known better and spared myself the sickness, but pizza is the one thing I haven’t been able to accurately replace with a gluten-free substitute.

If anyone out there has ideas about finding a good gluten-free pizza crust (or even a pre-made pizza! mmm) I would love to hear about it.  I’ve seen a few but they’re expensive and not available locally.  Any tips would be appreciated, thanks!
