This weekend I made Kim Boyce's Peach Ginger Muffins, they would have been great except for the fact that they had an odd salty/bitter after taste. This has happened to me before with other baked goods (not just muffins) and I have no clue what is causing it. I can't really find any common denominator between the recipes (one was an olive oil cake, the other cookies and the third being these muffins. Most of the ingredients that I used in the muffins were new (except the baking soda). Ideas anyone? I'd really like to avoid this problem in the future.
