Another Kai, how fun! You can try rolling your berries in a mixture of super-fine sugar and corn starch (50/50) before adding them to the batter. This will create a thin layer of sweetness that may prevent that sour smell. Still not what you are looking for? Try using dehydrated (or freeze-dried) blueberries instead, which have a great flavor and will tint the batter a beautiful blue! Good luck and happy baking! --Kye@ KAF
