What each ingredient does
- Carbonate of soda
- Alkaline base that reacts with the acid in the presence of moisture to release carbon dioxide for rising.
- Tartaric acid
- Acid that reacts with the carbonate of soda, providing the acidity needed for the leavening reaction.
- Ground rice
- Inert filler that keeps the soda and acid apart and dry until the powder is used.
The step that matters
Mix thoroughly. Uneven blending leaves pockets of soda or acid, so some batches rise unevenly or taste bitter. Sieving after mixing breaks up clumps and spreads the powders evenly.
