Making your own lemonade is the best way to control the sweetness. This recipe shows you how. Add sugar/sweetener to taste and use less of it if you don't want a sweet drink.
Stick to 1-1.5 oz alcohol per serving – Any more and the drink won’t freeze properly.
Yes, you can use lemon concentrate, but be sure to dilute it with water and add sweetener/sugar to taste.
