The story/lore passed from generation to generation is about the influence of a storm on some dishes. Allegedly, they sour once the storm hits. This holds especially when the dish is kept in a metal bowl, jug, or pot. What I've heard is that it affects soups, broths and mayo-based salads the most, but I am not sure if that is because of their ingredients or just because they are mostly kept in those metal containers.
Is there any scientific proof of this phenomenon, and if so what is the mechanism? Is it due to rapid changes in the air pressure or maybe electrostatics?
If that would be true, how can one counteract it? Does keeping dishes in the fridge help?
