baking powder




  • A chemical raising agent made from a finely ground mixture of two parts cream of tartar to one part bicarbonate of soda which liberates carbon dioxide gas on heating. Domestic baking powders replace some of the cream of tartar with an acid phosphate which is slower to act and gives more time for preparation and cooking.


  • noun a mixture containing sodium bicarbonate, starch and acids that is used to make cakes rise when they are cooked
