As tempting as it was to knock the whole bottle back as shots, I didn't commit myself to a month of shaking my mixture daily not to create some fabulous cocktails with it.
Apple and Blackberry is a ubiquitous combination for good reason, the flavours of autumn, they complement each other perfectly. This recipe is a version of one from the Difford's guide, with blackberry vodka in the place of muddled fresh fruit. Make sure to get good quality, sharp apple juice. The clear, sugary stuff from a carton would make this far too sweet. I got the Karmine pure Irish apple juice below from Fallon and Byrne and the flavour is incredible.
2 shots of blackberry vodka (I used a 50ml shot measure)
