Cooking is turning something that is inedible raw (most people regard raw fish, meat and most vegetables inedible raw) palatable by applying heat for a sufficiently long period.

Cooking for me is: melt a little fat in a frying pan, then add slab of meat or fish. Cover with lid. After about 20 minutes, add green vegetables. After about 20 minutes out into plate and eat. I use a mixture of spinach, broccoli and Brussels sprouts which I take out of the freezer the night before and defrost at room temp in a pasta drainer, excess liquid is discarded. Salt, pepper, herbs and spices as desired. Or not.

No weighing, no measuring, no fancy recipes from glossy magazines. But if you enjoy that sort of cooking the sky is the limit.
