I usually freeze my leftovers.
Then, when I reheat them, the flavors are diminished - less salt, less chili, less everything.
Any ideas why?
There are a variety of factors at work here:
Hope that gives you some ideas.
I asked this to a Swedish food guru and got the explication that freezing and reheating often softens the food. The effect is that each food piece has less time in the mouth before swallowing and therefore has less time to be tasted.
Not fully convinced but it might be worth experimenting with.
