Hi to all and thanks in advance. I usually make pancakes using the King Arthur basic pancake recipe. Rumford baking powder is used for rising; it's a non-aluminum based baking powder. Well, this time I switched to Calumet brand baking powder - aluminum based. I tested its activity in a glass of water. It fizzed. My pancakes, however, did not rise as high as it usually does with Rumford brand. I think that I'll stay with Rumford baking powder for the higher rise. Any of you ever had similar experiences with either of those baking powders?
