Limoncello, the sunny yellow liqueur that tastes like boozy lemonade, isn't a specific brand but a type of Italian spirit. This means that you might find a selection of limoncellos at any decent-sized liquor store, including some budget-priced bottles that shouldn't set you back more than $20 or so.

In fact, you can even make the liqueur yourself with nothing more than vodka, lemons, and sugar. Once you've acquired it, the question is how to drink it. Some liqueurs are so syrupy-sweet they really don't stand on their own, but limoncello has some sourness to balance the sweet so it can be enjoyed straight up.
