A cake is a very good test of an oven: if it browns too much on one side and not on the other, it's not your fault — you need to have your oven checked.
Although a food processor is not an absolutely essential piece of equipment, because you can certainly chop, grate, slice, knead and mix everything by hand, it does do all these things very quickly and efficiently and saves you time and energy.
There are people who claim to be instinctive cooks, who never follow recipes or weigh anything at all. All I can say is they're not very fussy about what they eat. For me, cooking is an exact art and not some casual game.
Food is for eating, and good food is to be enjoyed... I think food is, actually, very beautiful in itself.
