As something of a follow-up to my vanilla extract post (which is maturing quite nicely in the pantry), I took half of one of the beans and put it in a tupperware with about a cup of sugar, to see how long it would take to flavor it and whether I could do something with that.
The problem is, a day and a half later (and now a few days later), it's one solid lump. I guess it was the moisture in the bean, but something made it all clump together. It tastes fine so far (tried it in my coffee), but the results were disappointing. I can't very well give it away if it's clumping like old sugar. Did I do something wrong?
