Step 1

Rinse the fresh mint leaves and place them in a large glass jar.

Step 2

Cover the leaves with vodka until completely, or almost completely, covered.

Step 3

Let the leaves infuse into the vodka for several weeks.

Step 4

Strain out the leaves from your vodka. The strained liquid is a homemade peppermint extract! Save a little bit of it in a separate bottle for recipes, if you like.

Step 5

Dissolve the sugar in the water in a saucepan over medium heat, stirring until the sugar has completely dissolved.

Step 6

Remove the sugar solution from the heat source and let it cool.

Step 7

To finish making your liqueur, combine the sugar syrup with the homemade peppermint extract. This part can be done to taste. I used 3 parts vodka to 1 part sugar syrup and was happy with that concentration, but you can adjust that ratio to make your liqueur more or less sweet.
