With Suzie's providing the ingredients, it was very easy to make wonderful agua frescas for their Pumpkin Palooza this year. And boy did they go fast! Here's how I made them:
For about a 1/2 gallon of agua fresca:
about 8 cups watermelon chunks (or any melon your like), seeded and rinds removed
large handful of fresh mint leaves or lemon basil leaves (optional, and use whatever herbs strike your fancy)
a tablespoon of fresh squeezed citrus juice (lime, lemon or whatever you like)
Put all your ingredients in a blender and add water to cover at least half the melon (add more water as desired) and blend well. Strain liquid with a fine mesh strainer or cheese cloth (I use a rubber spatula to force as much liquid as possible through the strainer). Pour over ice and enjoy!
