Ingredients You’ll Need
To make a limoncello tonic, you will need…

Make A Gin Limoncello And Tonic
Don’t want to skip the gin? You could also make a limoncello gin tonic. Simply add some limoncello to your G&T for a pop of bright lemon flavor.
Feel free to play with the ratios but I like: 1 ounce gin + 1 ounce limoncello + 4 to 6 ounces tonic water.

- Add lemon slices: Garnishing with fresh lemon slices is also a nice addition.

FAQ
Limoncello is a sweet Italian lemon liqueur originating from Southern Italy. It is made from lemon zest, sugar and a neutral alcohol like grain alcohol or vodka. Limoncello is the second most popular Italian liqueur (after Campari). It is traditionally served chilled as an after-dinner drink (digestivo) but is also a popular ingredient in cocktails for a pop of lemon flavor without the sourness.
It kind of reminds me of sweet lemon hard candies. It tastes sweet with an intense lemon flavor.
You can find limoncello at the liquor store or make it at home. I prefer to purchase it since I know that the Italian lemons used are different from those that I will find at my local grocery store.
