A Keto Classic Margarita is definitely one of our favorite and easiest low carb cocktails to make. We replaced the sugar with Erythritol and cut down on the carbs but not the flavor!
The salted rim is completely optional, but it adds a nice savory touch that compliments the tequila and is very traditional on a margarita cocktail! Four ingredients and a jar is all you need to recreate this refreshing drink!
