Pink Sangria

I've made great red sangria and white sangria, and the next step was clearly the pink - kinda making it up as I go along since I don't have a recipe. Today I tried 1 sliced grapefruit, 1 sliced lemon, 3 red plums, 2 white peaches, a bottle of California Rosé and 3 Tbl. of watermelon rum. Will let you know the results. Once this is perfected, I plan to tackle Mango Mojitos and a Perfect Martini in the Cocktail Test Lab next.
