Cream of tartar is a fine white powder left behind in wine barrels during fermentation, used in baking to stabilise egg whites, prevent sugar crystallisation, and activate baking soda. One metric cup (250 ml) of cream of tartar weighs around 200 grams or 7.05 ounces. Most recipes call for it by the teaspoon, where 1 tsp weighs about 4 grams.

Cream of tartar is potent in small amounts. Even a quarter teaspoon makes a measurable difference to a meringue. Measuring by weight avoids the over-packing that comes with scooping, keeping results consistent.
