1 (15.2 ounce) bottle berry juice blend (such as Bolthouse® Blue Goodness®)
Instructions
Mix sugar and water together in a glass, microwave-safe, 8x8-inch dish. Microwave on high for 2 minutes. Mix with a fork until all sugar is dissolved. Stir in juice.
Freeze for 1 hour. Scrape mixture with a fork. Return to the freezer in increments of 30 minutes, scraping with a fork to create small granules after each one. The granita is ready when it resembles icy sand, about 3 hours total.
