Vegetable Oil

Let's talk about vegetable oil, plainly, the way I talk about everything in my kitchen — without fear.

Oil is fat, and fat is a carrier of taste and heat. Nothing more mystical than that. It coats the pan, it coats the food, it lets heat spread evenly instead of scorching one spot and leaving another raw. That is its whole job. A hundred grams of it gives you 884 kilocalories, all from fat, not a gram of protein or carbohydrate — rich and smooth on the tongue, the way pure fat should feel.

Choose it by the nose first. Good vegetable oil smells clean, almost nothing at all, maybe a whisper of the seed it came from. If it smells sharp, bitter or like old paint — put it back.

Some people say all vegetable oils behave the same in the pan. No! Refined oils tolerate high heat calmly; unrefined ones smoke and turn bitter fast. This misconception leads to a common mistake — pouring a fragrant, unrefined oil into a hot pan for frying, and ruining both the oil and the dish. Save the delicate oils for the plate, not the fire.
