This is the best homemade margarita recipe I've tried, and the easiest. Only 3 ingredients and nothing fake, neon green, or full of sugary chemicals in sight. They're tart and sweet enough, but not too sweet, and go down incredibly easy. I use freshly squeezed lime juice and recommend doing so. Agave is sold in nearly all grocery stores and big box retailers, although I've used honey in a pinch. The average-sized shot glass I use holds the same amount of liquid as a 1/4-cup measuring cup. It's easy to make the recipe in bulk. X parts this to Y parts that. Feel free to make a big batch and keep it for a few days in the fridge. While you could technically share the recipe as written, after having one, you'll want another. No sugar so you can sip worry-free, and they go down way too easily!
