Notes
If you don't have simple syrup on hand, its easy to make. Just follow the instructions in this post: https://selfproclaimedfoodie.com/make-simple-syrup/You can scale the sugar or lemon to suit your taste, but always start with a smaller amount of water. You can always add more, but you can’t take it out. I find that about 4 parts water to 1 part lemon juice is usually just right.Serving a crowd? This recipe is written for a single glass, but it's easy to scale:
1 cup lemon juice
1 cup simple syrup
4 cups water
Mix it all in a pitcher and serve over ice. Garnish with lemon slices or mint if you’re feeling fancy.
