Watermelon Margarita is slightly sweet and fruity margarita made with fresh watermelon juice, tequila, Cointreau, freshly squeezed lime juice, and just a touch of agave. If you're a fan of salty and sweet in a perfectly balanced sip, top your glass off with a salt rim and thank me later.
A pound of watermelon chunks will give you about 16 oz. of watermelon juice. Use as much as you need and store the rest in a glass jar with a lid, in the refrigerator. Use within 4-5 days.
To Make Watermelon Juice:
Cut watermelon into cubes and make sure to cut the rind off. Weight out slightly over a pound of watermelon chunks.
Place watermelon chunks into the blender and puree until completely smooth, no little chunks remain.
Strain the watermelon puree through a fine mesh strainer. (Stir the puree in the strainer with a spoon if it needs more help straining.) At this point, you can make the cocktails right away or store the watermelon juice in the refrigerator for later.
Watermelon Margarita:
Optional: Rub a rim of the glass with a lime wedge to get some juice onto it and dip it into the salt. Set aside. (You can also make a sugar rim the same way if you wish.)
Add some ice to the cocktail shaker and add reposado tequila, Cointreau, watermelon juice, fresh lime juice, and agave nectar.
Close the shaker and vigorously shake for about 20 seconds.
Add some ice to the glass, carefully so not to knock off the salt off the rim. Pour in the margarita into the glass through the strainer.OR, you can use the "dirty ice" that you used to shake the cocktail in the shaker, instead of pouring the cocktail over fresh ice.
Notes
Storing Watermelon Juice: When storing watermelon juice in the fridge, I recommend using a glass jar with a lid that's not made of metal. Metal tends to react badly when stored with foods that have acidic elements. These are the jars that I use at home (this is not an affiliate link): with coated lids and with hinged lids. When properly stored in an airtight container in the refrigerator, watermelon juice will last 5-7 days. Want to keep it fresh for even longer? Freeze it!
Freezing Watermelon Juice: Simply pour the watermelon juice into a freezer safe zip-top bag. Date and label it, then pop it in the freezer where it will last for up to 4 months. If you prefer, you can portion it into smaller batches, that way you can reach for it when you want to make individual cocktails instead of a whole batch.
