Cucumber Margaritas with Alex Thomopolous

I've seen some cucumber based cocktails, but never thought once of doing a cucumber margarita. Sounds interesting. The recipe also uses egg whites which is pretty interesting in a margarita also. Check it out below:

Recipe:
2 shots tequila blanco
3/4 shot agave
1 shot fresh lime juice
1 egg white
2 tablespoons cucumber juice
2 tablespoons simple syrup, equal parts water and sugar
Ice
English cucumber rounds, for garnish
