FVF observation of mine:
I bought my first tin of ABF, opened it, and thought "meh. . .good, not great". So I let it sit in it's square, not-at-all-airtight tin for a month or two (during the Maine winter, so it really dried out). When I tried it again it was amazing.
I have maybe 16 oz aging in various jars. I've sampled some that are now 6 months old, and it's not nearly as good as that crispy, dried out tin. In fact, I kept the last couple dried out flakes and stuck them in with some of the aging stuff, so I could compare.
I know all the conventional wisdom. And aging should be done with original humidity-levels, in a sealed environment. But has anyone else noticed that really dried out FVF is better than "properly" dried? Or, maybe, dried FVF ages faster?
