I'm a freestyle cook.
I never use a recipe.
Now and then I go online and get a vague idea of how long to cook an unfamiliar ingredient. Is it in minutes or tens of minutes or hours?
But I never use a recipe.
I don't own a single cookery book.
I don't own measuring cups. Or measuring spoons. Or a weigh scale. Or a kitchen timer.
I just open the fridge or (more likely) the freezer and ask myself "what's in here and what the hell can I do with it?"
Most of the time it works.
I have my disasters now and then, but most of the time it works.
