Here is my recipe, based on Allison's guidelines.
1 apple
1 orange
1 lemon
1 lime
1 mango
Handful of blueberries
1/3 C brandy or triple sec
1 C tequila
1.5 Liter bottle of wine, or 2 regular sized ones.
1 C sugar
Sprite, I used Diet Sparkling Sunkist Lemonade
At least 1 day before serving , cut up all of the fruit and put it in a serving container.
In a pot, boil one cup of water with the cup of sugar, until the sugar completely dissolves. Add the simple syrup to the container. Cover the fruit with the tequila and brandy, followed by the wine. Be sure to leave a couple of inches at the top of the container for adding in the Sprite right before serving.
Stir it a couple of times to mix the sugar, liquor and wine and then let it sit until just before serving. When ready to serve, stir the mixture. Then start adding the Sprite. Start about a cup or so of Sprite and taste. Sangria is best served over ice, so be sure to have a container nearby with some ice in it.
