Ahh... I didn't realize they had to be on the same form for that reason.
As for the lemon zest, some people do refer to it as a spice. That may be incorrect of them, but they do it all the same. (Not me, lemon zest is WAY too fancy for my RL cooking skills.)
I'm glad, though, that at least the lemon zest and vanilla got people to start posting in the thread again...I was worried I scared everyone off! ;p
