Ingredients
3 envelopes unflavored gelatin
1/2 cup white grape-peach juice
1/2 cup room temperature white wine (if not using vodka, use extra 1/4 cup wine)
1/4 cup vodka, optional
4 blackberries, cut in half
Directions
Boil grape juice in a small pot on the stove. Grease a 9 x 13-inch glass or metal baking tray with cooking spray.
Pour gelatin into a heatproof bowl. Pour hot juice into gelatin and whisk until fully combined. Let cool for no more than five minutes.
Add wine and vodka, if using, to gelatin mixture and whisk to combine.
Pour gelatin mixture into prepared pan.
Dot pan with 8 sliced blackberry pieces, making sure to leave even amounts of room to cut triangles.
Let gelatin set in fridge, about 2 hours.
Using a triangle cookie cutter, cut jello shots out of pan. Serve during the festive meal, and eat the leftovers as a snack tomorrow night.
