Baking Powder

Ingredients

Directions

Make the baking powder

  1. Sift the cream of tartar, baking soda, and corn starch together several times to ensure they are well mixed.

  2. Ensure the quality of the cream of tartar for a pure product.

Use the baking powder

  1. When wet, the baking powder will effervesce and release carbonic acid gas, similar to yeast.

  2. Bake the dough immediately after mixing to prevent the gas from escaping.

What each ingredient does

Cream of tartar
Provides acidity that reacts with baking soda to release gas when wet.
Baking soda
Supplies the alkaline base that reacts with the acid to produce carbon dioxide for rising.
Corn starch
Absorbs moisture and keeps the acid and base separated so the powder stays stable in storage.

The step that matters

Bake the dough immediately after mixing. Once wet, baking powder starts releasing gas right away. If the dough waits, the gas escapes before the oven sets the structure, so the rise is weaker.
