JELLO SHOT RECIPE
Take a box of sweetened, flavored gelatin. The most popular brand in the USA is JELL-O(R)*, but this formula works with generic as well.

For you carb cutters out there, I have made jelloshots with sugar-free gelatin. I've noticed no difference, nor has anyone else ever noticed.

Gelatin desserts come in usually 2 sizes, 4 servings or 8 servings of 1/2 cup each. Either works well.

Step 1 - Choose your recipe. Vodka or rum works with any favor, but you can be creative. Some suggestions.

Citrus flavored vodka + peach jello = Fuzzy Navel

Captain Morgan Spiced Rum + pineapple jello = Mai Tai

tequila + lime jello = margarita

You get the idea!

Step 2 - Go shopping. You'll need the following
Flavored gelatin in your desired flavor
Enough booze - 50% of the added liquid should be 80 proof, or 60 proof.
Cups to house the jello shots. I use 2 oz. clear plastic with lids, I got them at Costco. In a pinch 3 oz. wax paper cups work, but get messy.

Step 2 - Freeze the liquor!!!!!!!!! This is really important to both expedite the setting-up of your jello shots, but it also reduces alcohol loss due to evaporation! Do this the night before. Don't worry, any booze over about 40 proof won't freeze or explode. It gets a bit thicker, kind of neat.

Step 3 - Bring 1/2 the liquid to a boil in a pot on the stove. Add the jello mix, turn off the heat. Stir for a minute or two, ensuring the jello is fully dissolved. Add the pre-measured booze. Stir briefly, then dispense into the small cups.

Step 4 - Carefully put the caps onto each container. If no caps are available, place the open-topped cups on a cutting board in a 4 by 5 cup array or so. Cover these with cellophane. Place a sheet of cardboard on top of this, and make another layer. Don't go more than three layers or you really risk a spilling disaster. If your cups are covered in cellophane, plan on serving in no less than 3 hours and no more than 8 hours. Otherwise, the alcohol evaporates off. Bummer. If you have tight-fitting plastic lids, I think they would last a few days, but I've never made enough to last after the first night. The night before is usually best.
