750 - 1000mlof good quality vodka (nothing cheap, but not top shelf)
Instructions
Place cucumber slices, dill and black peppercorns in a jar with an air-tight lid. Add vodka to cover the ingredients (I used just over 750ml). Let infuse for 4 days in a cool, dark spot.
Strain infused vodka into a clean jar or bottle. Discard solids. Infused vodka will keep in the fridge for up to 1 month or the freezer for up to 4 months. The vodka won't go bad, but flavors will start to dull as time goes by.
