Ex Input:
I used this mix to make a 9x13 cake in a glass pan using grapeseed oil, spring water, and free range eggs.  I thought the cake had a nice flavor to it but it was not what I was expecting.  I was craving a white cake (like wedding cake) and went to my local store to find something wheat-free, gluten-free and dairy-free; I purchased this vanilla cake mix.  I think it is a very good mix.  I couldn't really taste the vanilla flavor but thought it had a nice flavor.  The cake is yellow, dense (but not like a pound cake) and texture-y like brown rice has more texture than white rice.  I thought the sweetness was just right.  I think I would purchase again but would make pineapple upside down cake with it.

Ex Input:
Very firm small pieces with an intense licorice flavor. I love black licorice and have been trying different gluten free options. I will be ordering more of this one.

These are definitely not worth close to a dollar a piece.  If they were at my local grocery, I might give twenty to thirty cents per can for them.  I didn't really like the flavor that well, but if you did, they might even worth up to fifty cents per can.  Otherwise, pass these up.
