Here’s something really impressive to try for your party. Jell-O shots are a popular party favor and can come in almost any flavor imaginable. Here I will share Boozy Watermelon Jell-O Shots. It is a sweet treat for adults (swap out the water with vodka).
What you will need: (about 30 shots)
- 1 12–16 pound watermelon
- 4 cups vodka
- 4 3-ounce boxes red Jell-O
- 2 1-ounce boxes unflavored gelatin
- Paper towels
- 2 large bowls (one to mix the Jell-O, one for the watermelon you’ll scoop out)
- 2 small sheet trays or baking dishes (each needs to be big enough to fit a watermelon half)
- Liquid measuring cup
- Electric kettle (or you can boil water another way)
- Cutting board
- Kitchen spoon
- Whisk
- Chef’s knife
Steps:
- Cut the watermelon into two equal halves (lengthwise) with a large chef’s knife, c.
- Use your knife to slice all the way around the perimeter of the watermelon flesh, about an inch from the rind. Be careful not to pierce through the skin, as this will lead to your Jell-O leaking out. Then use a kitchen spoon to scrape out the rest and create a smooth bowl with roughly 1/2-inch red watermelon flesh left on the rind.
- In a large mixing bowl, combine the Jell-O mix and the unflavored gelatin. Add 4 cups of boiling water and whisk until the gelatin is completely dissolved, about 2 minutes. Add the vodka all at once and whisk just to combine.
- Pour the Jell-O mixture into the watermelon bowls, dividing evenly.
- Put two folded paper towels on opposite sides of each tray. watermelon bowl will lie in the middle.
- Carefully place the tray in the fridge, and refrigerate until set, about 4 hours.
- When Jell-O is set, cut each half into 1-inch slices, crosswise, then cut each slice into 2–3 wedges, and serve.
