>>1 I started cooking with my mom. We would always cook together for I could remember, and she taught me the basics. Then, I had to go on and teach myself the rest.
I'll give you a few good foods to start with so you've got a good process and know what to look for. You have to look it up or experiment yourself to figure out how to actually make them; I'm not a walking cook book.
The sandwich! Ah, the glorious sandwich! There is so much to do with it, it's like a blank canvas. Raid your cabinets and take out everything you want to use. Those are your paints. Then get to making something.
Grilled bologna and cheese is a great way to start. You learn what order things need to be done in so that everything is melted. You'll figure out what temperature is best, when it sticks, how much butter you'll need, and when to flip it. All these things are the basic essentials to cooking.
Then, move to pasta.
Spaghetti and meatballs are another big deal. By learning to make this, you'll understand boiling, the ratio of pasta to water, how often to stir, when to let it sit, how to tell if it's ready or not. You'll learn how to tell if the meatballs are ready, when to put the sauce and balls into the spaghetti/the effects of doing so, et cetera.
Pancakes and eggs! Pancakes and eggs are great ways to get used to different pans. You'll learn how non-stick they really are, and you'll understand how much butter is needed to save those pancakes. You'll get used to learning the temperatures on different burners the more you make it (since they're both so sensitive), which is good for future reference, as well as how to flip things on the various pans.
As you get better?
Pork chops! They're a great canvas for different flavors. Get used to putting these different flavors together utilizing this cheap yet great food.
Fried Chicken! What temperature should meat be at when it's ready? What oil to food ration should you use? Should it be salted? What flavors show and what flavors disappear after frying? What temperature shold the oil be? These are indespensible lessons with cooking.
Sauteed onions/mushrooms! Practice the dry heat cooking method. See how small mushrooms get. Feel the difference in texture between onions before and after cooking.
Well, good luck!
