A lot of good cooking is in technique. What’s something that you discovered or was told that really changed something meaningful for you? For me, I had struggled a lot to make omelettes. They always wound up becoming scrambled eggs because I sucked at flipping them over to cook on the other side (I like my eggs cooked pretty well so this was important to me.) Finally, watching someone else make an omelette, I noticed they didn’t flip it. They put a lid on the pan, turned the heat down, and let the top cook that way. I tried it myself and now I make almost perfect omelettes every time. Have you had anything like this happen to you? If so, what was it?
Learning how to properly sear food them let it cook the rest of the way over low heat. Potatoes, chicken, etc.
Kind of the opposite of that, sous vide steak then sear with a screaming hot cast iron pan.
The broiler in your oven is fantastic for toasting buns and melting cheese on top of stuff. Also good for putting some char on your food if you need that.
