Hi, I actually just did a google search for fishy taste in choc-chip cookies and this thread came up. I made a batch of choc-chip cookies a couple of weeks ago and two people mentioned that they had a fishy taste. As I bake to supply cafes - this isn’t good feedback. I’m convinced that it is either the butter or the chocolate I’ve used, as I’ve made them before and not had this problem. Admittedly I use gluten-free flours and the bean flours can impart unusual tastes if used in too high a quantity. But this isn’t the case with my flour mixes. Also my flours are all fresh, as I grind the grains myself. My oven is clean, so dripping from above can’t be a problem…. Also at the same time as baking the cookies, I baked a number of other cakes and biscuits and none of them had this taste…. I can only conclude that it must be the butter or chocolate that I was using. Any other ideas or experiences of this?
