The chef instructor screamed, “Lie. Lie.” (Pronounced lee-ay), from across the kitchen. My cooking partner and I flinched with terror as the chef ran across the floor raising a piece of paper, “Lie! Lie!” As he approached our cooking station, he threw down the piece of paper, and with frustration pointed at the recipe printed there. I read the word Lie and its definition under his manicured fingernail, "Consistency of a liquid to coat back of metal spoon." He was trying to explain to me how to check the thickness of my sauce by dipping a spoon into it and running my finger through it. If the line drawn by my finger holds, then the sauce is thick enough.
I still do not understand all the excitement, but it was obvious that he was trying to teach me something. Nonetheless, there may be only one way to check the consistency of a thick sauce or soup, but there are many ways to actually thicken.
