Test Kitchen Tips:
•Substitute blackberries in place of the blueberries. Strain mixture after blending if you prefer to remove seeds.
•Calamansi is a citrus fruit similar to lemons and limes. The ripe fruit is juicy, tart, and varies from green to yellow-orange in color. Popular in Filipino cooking, calamansi juice is often used as a marinade or squeezed over noodles. In America is it sometimes called calamondin. Calamansi juice can be found in some grocery stores as well as online retailers.
•To shave ice cubes, place about 2 cups ice cubes in food processor. Pulse until desired texture, usually about 10 to 20 seconds. Remove any remaining large chunks of ice. Use immediately or store in freezer until ready to serve. 2 cups of ice cubes should yield about 2 1/2 cups of shaved ice.
•Use to create slushies or granitas. Pour the lemonade mixture into a freezer-safe container. Place in freezer. Stir and scrape every 20 to 30 minutes as the mixture freezes to create a refreshing icy texture. Enjoy when lemonade has reached desired texture.
