When cooking, you're supposed to smell and taste your food. All the great ones say this. When smelling your food, you're not supposed to just stick your nose over the pot; you're supposed to lean down kinda-sorta close to the pot and wave the aromas of your food toward your nose. All the great ones say this, too.
Oddly, the great ones are mum on the subject of whether or not you're supposed to close your eyes and furrow your brow and look like you're trying to commune with the dead rather than just smelling the vegetables and meat you're sauteing.
And holy crap, my hands look big here. They're not that big. Really.
