Note 1: Giada originally calls for Blackberry jam which is excellent, but we've found many variations to be equally or even more delicious. Try a nice homemade strawberry jam or some unique jam in your cupboard. Marmalades are a great choice too. If using homemade or boutique jams, make sure the jam isn't too runny.
Note 2: For a quick piping bag, place jam in a quart size ziplock bag and snip one of the bottom corners off of the bag to create your piping hole.
