Inconsistent Soapy Taste
Hi all! Newbie here. I usually make breads and muffins from oat flour. I recently started using certified gluten free oat flour. I had a batch of muffins come out with a soapy taste. I tried a different recipe with the GF oat flour - no soapy taste. Tried the original muffins (with conventional oat flour) - no soapy taste. I used the same baking powder in all recipes. Anyone have any thoughts on why just one out of three batches would come out tasting soapy?
