About Cream of Tartar
Cream of tartar is an acidic powder used in some meringues and leavening mixtures. It is not baking powder on its own. Check the ingredient name carefully, especially on packets of premixed raising agents.
Measure with a dry, level spoon. A scale displaying whole grams may not resolve the small amount required for egg whites. Follow the recipe's dose and whipping method; adding more powder cannot repair every collapsed foam.
Tips for measuring Cream of Tartar
- Keep the powder dry and break up lumps before measuring.
- Use a fractional measuring spoon for a specified fractional dose.
Common mistakes
- Confusing pure cream of tartar with a baking powder mixture.
