Stay as close to the actual cap size as possible, because you will eventually place your vodka bottle inside the hole that you’ve carved, and you want the fit to be snug so there are no leaks.

Continue cutting around the traced circle until the entire circle is carved around.

This will create a wedge that can pop the watermelon plug out of the carved hole. Refrigerate the watermelon plug in a re-sealable plastic bag so that you can reinsert it later. Save the vodka bottle cap to seal the vodka later.

Be careful of watermelon juice and pulp splashing. This can make your workspace wet and sticky.

If you have a friend nearby, they can hold the watermelon up and in the air a little bit and guide it to meet you, holding the opened vodka bottle. Your vodka bottle will be at about a 90 degree angle to you, and parallel to your work space when you insert the bottle.

The vodka should absorb about half, to the whole bottle of vodka.

You can cut the watermelon into wedges, or peel it and cut it into cubes.

Don’t worry about removing the seeds, they will be strained out later.

Watermelon flavors will infuse faster when you cut them smaller since the fruit has more contact with the vodka.

The vodka should look pink. Throw out the watermelon chunks, or if you’re feeling really daring, wrap the pieces of watermelon in plastic wrap, refrigerate, and eat later.

This method can be used with other flavors of candy too.

You might want to shake the jars to try and dissolve the candy faster, but this doesn’t really dissolve the candy faster.

At first, the flavor of the vodka will taste just like the watermelon candy you used, and then the vodka taste will come through. These can be served as shooters, or used for flavored martinis. [7] X Research source
