I know that this has nothing to do with cakes, but I had the most amazing pie at Knotts Berry Farm in California. I've been looking for a shop in the Dallas/Fort Worth area that might carry it, but no luck. Would anybody know of a place around here??
if you can find boysenberries in a local supermarket (HEB? I bet they'd have them) -- then take a stab at making the pie yourself.
all kinds of recipes all over the net for it. Just your basic fruit pie. (remember the cookie sheet to catch the drips!)
look at this (definitely can make yourself)
Unfortunately, we don't have HEB in our area, but that other option is great!!! Thanks, Doug!!!
