Breanne Rupp of Boat Drinks Bar in St. Augustine, Florida sent along a recipe for a "foolproof leftover coffee grind liqueur".

I put it in parts because it scales really easily this way but if parts are converted to cups (for at home making, not weighing out ingredients like at a bar) it yields a bit over 1L.

Foolproof Leftover Coffee Grind Liqueur

Ingredients:

1 part leftover coffee grinds

4 parts sugar (basic granulated white sugar is easiest/cheapest to work with but you can experiment with other types or just use what you have)

2 parts liquor (80 proof is ideal, vodka works great as a neutral base but again, again, use what you have or what your palate prefers)

2 parts coffee (the stronger, the better)

Pinch of salt

Optional: citrus peels & cabinet spices. My favorites are orange peels, cardamom, cinnamon, clove, star anise, vanilla... again, lots of room to customize and play with what you have

Directions:

-Combine your coffee grinds with your sugar, salt and any additional spices/citrus peels in an airtight container. Leave this for about a day, stirring/shaking intermittently. The sugar will begin to dissolve and turn sludgy.

-The following day, add your base liquor and again, stir/shake intermittently allowing the liquor to infuse for about one more day.

-Pop everything into a blender to fully dissolve the sugar.

-Pass through a basic mesh strainer first.

-Fine strain through a nut bag or clean thin fabric (old t-shirt, bandana.)

-Add 2 cups of coffee and give a good stir/shake to incorporate.

-Store in an airtight container in the fridge.
