Arnold Palmer jello shots! 1 box lemon jello, Firefly sweet tea vodka, 10 lemons. Cut the lemons in half, juice them, pull the pulp and skin out (I did it with my hands, but make sure your hands aren't dry at all or it will burn!) Line the halves up in a cake pan so they're snug. Then make the jello, put the mixture in a measuring cup with a spout for pouring and fill the lemon halves. Refrigerate over night and then slice in half again (with a sharp knife) before serving.
