Step 1: Find some nice juicy oranges (or lemons or limes) to squeeze! The kids bought me an electric citrus juicer for my birthday, and it is wonderful. We are blessed to be able to find fresh citrus year around here in Oaxaca.
Step 2: Find an assistant to help taste the citrus.
Step 3: Mix the juice and sugar. You will need about 2-3 cups of juice. Add sugar to taste (~1/4 - 1/2 cups for orange or more for lime/lemon).
Step 4: Add plain or mineral water (we used mineral water here).
Step 5: Enjoy! It makes a great drink for Family Game Night (every Thursday at our house)!
