If you have the fridge space, chilling the watermelon the night before will give you a quick chill on the margaritas. The ingredients are to taste, so add as much as you like based on your personal taste preference and adjust as needed for different sized watermelons. A watermelon about 7-10 pound will be a good size that will allow the beater blades from the hand mixer to reach all the way through and around the inside of the watermelon. If your watermelon is any larger, you might need to use an immersion blender with a longer reach or use the drill and coat hanger method. Watch the video to see how we made these. Hand held blender works fine and you just have to blend a little longer if you want a more liquid texture. For the most smooth and less chunky results, we like to use our immersion blenders.
8lb.(3.63kg)ripe watermelon -If it is larger than 10 lbs. the beater blades won't reach inside to blend
2/3cup(160ml)Tequila, or to taste
1/3cup(80ml)fresh lime juice, or to taste
1/3cup(80ml)orange liqueur(i.e. Grand Marnier, Cointreau, Triple Sec)
Carefully cut a hole in the watermelon large enough to fit your beater blade. Push the blade into the watermelon hole and slowly blend the watermelon interior into juice. Make sure to scrape all the way to the sides and bottom of the watermelon to maximize juice.
Ladle out about 1 cup of watermelon juice to make room for the rest of the liquid ingredients. You can reserve the 1 cup of removed juice and make a separate margarita later.
Add tequila, lime juice, and orange liqueur. Insert the beater blades back into the watermelon to mix the margarita and combine all the ingredients.
Make Pour Spout: Cut out the bottom of a paper/plastic cup. Cut out a section of the cup so it fits into the watermelon hole to use as a spout to pour. If necessary, round out the hole in the watermelon so the cup fits smoothly against the edges and insert the cup into the watermelon hole.
Rub some lime juice on rim of glasses and roll rim in sea salt (optional). Add ice to glasses and top with watermelon margarita and lime garnish. Enjoy!
