This recipe appears in:DIY vs. Buy: Should I Make My Own Sour Mix?
The true beauty of making this mix is having a fresh, versatile, and easy cocktail mixer for parties. There's no reason to buy sour mix when in 10 minutes you could hand-make something that's infinitely more delicious.
If you'd like to use oranges, grapefruits, or agave nectar, keep in mind that they are sweeter than the ingredients in this recipe so you'll have to adjust the quantities to taste. Refrigerate the mixture, and it should last a week or two. (You can tell it's turning if it starts to get cloudy particles.) Adding a little vodka will make it keep a month, but it won't taste as fresh after a long storage.
- 1 cup sugar
- 1 cup water
- 1 cup freshly squeezed lemon juice
- 1/2 cup freshly squeezed lime juice
Make simple syrup by bringing the sugar and water to a boil, about 7 minutes. Stir to dissolve sugar. Remove from heat and let cool.
While the syrup is cooling, strain freshly squeezed lemon and lime juice into a resealable bottle, discarding the pulp. Pour in the cooled simple syrup. Shake and use immediately or refrigerate.
