You should also definitely serve them in pretty glasses. Pretty glasses make everything taste better. This mix is essentially what you would call a "simple syrup" mixed with fresh lemon & lime juices for a perfect sour mix. Simple syrup is 1 part sugar to 1 part water- I've also read that you can do 2 parts honey to 1 part water but I haven't personally tried that yet! Let me know if you do... The best thing about making your own mix is that you can make it super sweet if you love a sweet margarita or more sour if that's your thing.
For the Simple Syrup:
1 Cup white sugar
1 Cup Water
For Sour Mix:
Juice of 1 lemon
Juice of 1 lime
+ 1 Shot of good Tequila per margarita
Step 1: Combine sugar & water in a heavy-bottomed sauce pan and stir well. Heat on high, stirring frequently until the mix comes to a rolling boil. Whisk until sugar is dissolved and remove from heat.
Step 2: Transfer sugar- water mixture to glass containers, cover & chill completely. A mason jar would be perfect for this step- I just couldn't find any of mine, I've apparently left them scattered all over the U.S. this past year and had to go buy a new case...
Step 4: To assemble margarita: Over ice, in a salt-rimmed glass if desired, combine 1 shot (1.5 oz.) tequila, 1 shot simple syrup (sugar water mixture), and half a shot of lemon- lime juice mixture. Stir well, garnish with a lime and enjoy!
