Cream of Tartar

Cookbook | Recipes | Ingredients | Equipment | Techniques | Cookbook Disambiguation Pages | Ingredients

Cream of tartar, also called potassium hydrogen tartrate or mistakenly called tartaric acid,[1] is an ingredient byproduct of wine making.[2][3]

Characteristics

edit

The substance precipitates out of wine and accumulates in the vats, after which it is harvested and refined into a pure white powder.[4][5] It is mildly acidic, with an otherwise neutral flavor.[6]

Selection and storage

edit

Cream of tartar should be stored in an airtight container at room temperature. It has a very long shelf life.

Cream of tartar's primary uses come from its acidity. When added to egg whites during whipping, it helps coagulate the proteins and stabilize the foam[2][5][6][7]—2 tsp per 1 lb whites (20 ml per 1 kg) is recommended.[8] It also often makes up the acidic component of baking powder,[4][7] and it can help reduce crystallization in sugar syrups,[4] as well as add a neutral sour profile to preparations.
