Which totally reminds me that I have to go make another batch of syrup...
Here is the awesome recipe I am using:
Step 1: Go out to BevMo or some other liqueur place (don't worry, you're buying non-alcoholic stuff). Ask for Torani brand "Italian Soda syrup" flavored Creme DeMenthe. Make sure it is non-alcoholic!
Step 2: Go out and grab Natural Lime juice (usually found with the "cooking" supplies of your local market) and grab Frozen Lemonade mix (found in the Frozen Juice section of the Freezer department).
Step 3: Go and throw the Frozen Lemonade mix in a medium-sized bowl when you get home, and let it thaw until it is liquid.
Step 4: Follow this recipe and measure out the materials accordingly:
1 cup Sugar
3 tsp. Lime Juice Concentrate
3 cups Soda Water
6 tbsp. Creme DeMenthe (hard to find, but this is important)
6 oz. thawed Lemonade Concentrate
Step 5: When you have the Lemonade, Lime, Soda Water, and Sugar, all measured out, put them in a pot and boil.
Step 6: Put it off the flame when it is boiling and allow it some time to cool down.
Step 7: Throw in the Creme DeMenthe syrup: your liquid shall now become a minty green color (as seen on the VMK pins).
Step 8: put the Mint Julep syrup in the freezer, and give it twenty minutes or so. You want it to cool down, but not to freeze.
Step 9: Put the syrup in a large tupperware bottle, and pour enough syrup into
your drink, so that the liquid reaches nearly the halfway point in the cup.
Step 10: At this point, you put in
Diet Sprite for a little extra bubbly+Limon flavor. Fill up the rest of your glass with Diet Sprite, and enjoy your Mint Julep.
