Now, what a difference the wine makes, while Doug's sangria looks like the pale red of the watermelon, my version looks much deeper and yes, you got it right I used red wine. Actually, I skipped the agave nectar, because I used a slightly sweet red wine.
This red is very happy served chilled and hence, just perfect for Sangria. I had to through in the black salt, it is a quintissential Indian combination to add black salt to fruit juices.
So I made about 4 glasses of sangria following the following measures,
Watermelon Sangria
Cook/Prep Time: 1 hour (mostly chilling)
1.5 cups of fresh watermelon juice (about 1/2 a medium sized water melon, cut and pureed in the blender and then strained.
1.5 cups of a sweet red wine
1/2 teaspoon black salt
1.5 cups of seltzer
Method of Preparation
1. Mix in the watermelon juice, red wine and black salt.
2. Chill for at least 45 minutes to an hour.
3. Place 2-3 ice cubes in serving glasses (you do not want too much or it will dilute the watermelon flavor).
4. Add in 3/4 glass of the wine-watermelon mixture.
5. Top off with some seltzer and enjoy.
