  2. Spray a silicone mini muffin or candy-making pan, with a volume of 2 to 4 tablespoons per cavity, lightly with cooking spray. Wipe the excess spray from the pan so there is no visible residue.

  3. Pour lemonade into a small pot or deep pan and sprinkle with both packets of gelatin. Let sit off the heat for about 2 minutes until gelatin “blooms.” You’ll see a ripple film form on the top.​

  4. Put the mixture on a low heat. Heat and continually whisk until the gelatin evenly dissolves about 2 to 5 minutes. Be careful not to let the mixture come to a boil.

  5. Remove from heat and let the mixture cool a bit. Whisk in the vodka and sweetened condensed milk.

  6. Divide the mixture evenly into 6 separate bowls. Put a few drops of different colored food coloring in each and whisk to thoroughly mix.

  7. Spoon about 1 teaspoon of the first color mixture into the pan cavities. Refrigerate until just set, usually about 20 minutes. Do not allow to set too long because if they are still a bit sticky all the layers will set together better.

  8. Repeat with all colors, letting each layer set for about 15 minutes between. Refrigerate overnight.

Tip

  • The shots should slide easily out of the muffin pan but you may need to do some careful prodding with a small offset spatula. Once out, you can top with frosting or whipped cream and sprinkles.
