Ever had real ginger beer? This is a refreshing beverage made with just four ingredients. If you find it too strong, or if you like some pizzazz in your drink, combine it with seltzer water in a ratio that works for you.
1 pound fresh ginger, grated
1/2 cup fresh lime juice
1 cup brown sugar, or to taste
In a saucepan, bring 3 quarts of water to a boil, then remove from heat. Add ginger and steep overnight.
Strain mixture through a fine-mesh sieve, pressing ginger to release flavor. Pour into a pitcher or bottle using a funnel. Add lime juice and 1 cup sugar; stir vigorously. Cover and store at room temperature; let mixture steep (and dregs settle) 24 hours. Decant to a second bottle with a tight-fitting screw top and refrigerate for 3 to 5 days.
