Blueberry-Lime Agua Fresca

• 8 cups blueberries, rinsed and stemmed
• 6.25 cups sparkling water (two 750-ml bottles of Pellegrino), see notes above
• 1/4 to 1/3 cups fresh lime juice
• 1/4 to 1/3 cups light agave syrup, see notes above
• fresh mint sprigs for garnishes
• ice for serving

1. Puree the blueberries in a food processor or blender with one cup of the water until smooth. Pass the puree through a fine-meshed sieve held over a large bowl. (Note: If you are using a high-powered blender such as a Vitamix, you may not need to use a sieve.) Press with a spatula to help the puree pass through the sieve. If necessary, add water to help loosen the puree to make it pass more easily. Once you are left with a considerable mass of blueberry solids in the sieve, return it to the food processor or blender and puree with another cup of water. Pass this mixture though the sieve one more time.
2. Add the remaining water to the bowl with the blueberry puree. Add 1/4 cup of lime juice and 1/4 cup of agave syrup and stir to combine. Taste. Adjust with more lime juice or agave syrup by the tablespoon to taste, adding as much as 1/3 cup of each total. Transfer agua fresca to large pitcher.
3. Fill glasses with ice. Nestle in mint sprigs. Pour in the blueberry agua fresca.
