I chose apple and lemon. Chop them up into fine little piece. The amount is up to how much vodka your using. Estimate ;).
Store them into a container.
Add Vodka! Fill it up!
Keep in fridge for atleast 2 weeks for it to be infused (Its a pain to wait! But its worth it!)
Tips: the longer you wait, the better. But if te fruits are turning brown then i suggest you change it.
