So I thought this was genius when I read it in How to Cook Everything (a must have cookbook, especially if you are starting out).
So I am usually doing too many things at once. I’ll put some oil in a pan and let it start to heat up, get busy with something else and then return to the pan not knowing if it has been heating for 10 seconds or 10 minutes. An easy way to get an idea of the temperature is to put your oil in along with a dollop of butter. As the oil heats up the butter will too and you can actually see the butter melting a cooking. It isn’t an exact science but gives you a visual to keep track of the temperature. Happy cooking.
