Yes, you could go to the store right now and buy pre-made Margarita mix. But, we promise you it will not taste nearly as good as if you made the mix yourself. Most Margarita mixes—regardless of who makes them or if they’re craft products—are generally more sweet than sour. Even with natural sweeteners, mixes will lack the vibrant acidic kick of fresh squeezed lime juice, which is exactly what a good Marg needs. So if you want to make the best Margaritas at home, without having to squeeze limes for each drink individually, make your own DIY Margarita mix.
All you need to make the mix is a big bag of limes, a few oranges, some agave syrup (a combination of water and agave nectar) and sea salt. Simply press the citrus, add the juices to the agave syrup and voila, you are officially ready to make yourself a slew of Margaritas. If you want your mix to keep longer than a couple of days in the refrigerator, we suggest adding half a teaspoon of citric acid to the mix (which will extend the shelf life up to a week). The extra acid will not only act as a preservative, but also boost the flavor of the lime juice, making your Margarita even more bracingly sour. Don’t worry if citric acid seems like a difficult ingredient to find; you can buy it online. Best of all, once you buy one bag, you will have enough to make several batches of this mix.
