These are a lot of work, but you'll get a big 'wow' when you serve them. The filling is delicious, and the buttery cookies just melt in your mouth! The cookie dough recipe comes from TOH magazine, and I made the filling recipe up myself. I think it'd would be great if you had a heart shaped cookie cutter, and used strawberries and strawberry jelly instead, for valentines day. For 1/2 quart of blueberries, I poured in half of a quart sized bag of homegrown.
