Thanks for the replies. I looked at my LHBS, but didn't see any extract. Of course, I didn't ask either, so maybe I'll hit them up about it next time I'm in there.
As for the purée, where would I find it? I looked in Publix here in FL and all I found was raspberry pie filling, jam, and jelly. I haven't made a concerted effort to find any yet, so I'm just asking.
