These little gems are not new to the pantry and I love them with just about anything you want to fill them with. My favorite is sour cream raisin filled, but my family like boysenberry jam from Knott's Berry Farm.
There is an art to getting them sealed so that all the jam doesn't leak out while baking. My grandmother use to dip her finger in a little bit of cream and rub it around the edge of the bottom cookie before placing the other one on top.
If you would like to bake a long with our group.... Check us out at Tuesday's At Dorie.
