Tamarind / Acid

Tamarind concentrate by the 14oz or 19.4oz jar for the pad thai sauce and the som tam dressing, lemon juice and rice vinegar for the cold side, white vinegar by the gallon for everything else. มะขาม is the sour leg of the Thai-flavor stool and a kitchen that runs out of it on Thursday will hear about it in the pad thai by Friday. The cook knows the jar they want by weight.
