Potassium Bi carbonate

Potassium bicarbonate is widely considered to be one of the best substitutes for baking soda in a recipe. This is because potassium bicarbonate has the same leavening capabilities as baking soda, but there is one distinct difference: it does not contain any of the sodium that baking soda possesses
