I am a decent cook...not professional-level, but I know most of the basics of roasting, broiling, braising, poaching, pressure cooking, boiling, frying, grilling and baking.
I cook a wide variety of things. I tend to make things which allow me to make multiple servings of one food and have leftovers. But for seafood and certain grilled items, I try to get a single serving since it's usually not as good the next day.
I bake a decent amount as well. Usually, it's just cookies, muffins, scones and quick breads, maybe I'll do something twice a month. Every year, I'll make 3-4 fancier things like a pie or an iced cake. And maybe once a year, I'll do some really fancy thing...this year, I made an Opera cake (which was REALLY good).
My freezer is stuffed with stock, leftover cookie dough, fully baked goods, mini casseroles and other items that I can use to whip something up with minimal effort. When my freezer gets full, I have to force myself to stop making things.
I'd say favorites are Mexican cuisine (including more involved things like carnitas), braised dishes and breakfast foods. I'm currently working on trying to refine my pizza making technique...my crusts are getting better, but I think I have to invest in a baking stone to take it to the next level. I'd also love to get into barbecue, but I live in an apartment

, so I may try "sous vide barbecue" as an alternative for my next cooking adventure.
