Earlier in the season I picked up some TJ Pure Bourbon Vanilla Extract. Like a fool I didn't taste it.
Weak vanilla aroma, bitter, and harsh alcohol. Not at all like good vanilla should be.
It has tainted 3 batches of cookies. I shrugged off the first batch, as I was using up a bag of flour, thought that was it. New flour, fresh butter, and next batch: bleagh! So I tasted the vanilla--cheap and awful. Never had trouble with their vanilla in the past, but now I know.
My fault for not tasting it and I will return it--but BEWARE if you are getting a late baking start as I am. Test your vanilla first if you haven't used it before.
