Gift Idea: Homemade Limoncello
There are plenty of recipes online but I used this one, and liked the ratio of sweetness to alcohol. I let the peels sit for about 1 month in vodka, then added the simple syrup, and waited another 3 weeks before tasting. It will only get better the longer it sits!
P.S. Some recipes call for Everclear or grain alcohol but it's not available everywhere. I still liked the taste of the vodka. I think I might try doing a blueberry vodka next, or an orange infusion. So many possibilities!
