This recipe is my go-to for flavouring vodkas and it’s easy to scale to whatever size you want, but my default is 500ml. The hardest part is leaving it and not succumbing to the temptation to taste it before it’s ready! I tend to use a standard vodka like Smirnoff to flavour – if you use anything too good it will kill the flavour, and paint stripper-levels of vodka will always taste of paint stripper, no matter what you flavour it with.
Take a clean, sterilised clip-top jar and to it add about 100ml of vodka and the sugar. Seal and shake to dissolve most of the sugar.
Hull and quarter your strawberries (or half if they are little), add them into the jar. Pour the remaining vodka and the basil leaves in. Gently shake to mix everything together. Put in a cool, dark place.
Leave the jar for two weeks, gently swirling every two-three days.
Filter out the vodka – I use a kitchen paper-lined sieve, but coffee filters also work well – and put into sterilised bottles.
