Add lemon juice, Averna Amaro, and orange flavored vodka in a cocktail shaker.
Add ice and shake well.
Strain over ice in a short glass with fresh ice.
Top with ginger beer.
Notes
I prefer to use Meyer lemons since they are a little sweeter but regular work fine too. I use homemade flavored vodka but you can use store-bought or plain vodka. Nutrition information will be slightly off as the software didn't have Amaro as an option. This would also be fantastic muddled with fresh orange pieces, berries, or even peaches.
