Step 1: Prepare the Lemon Juice. Start by squeezing enough fresh lemons to yield 1 cup of freshly squeezed lemon juice. Strain through a sieve.

Step 2: Combine Ingredients. In a mixing bowl, combine lemon juice, sugar or honey, and water. Whisk until dissolved, about 1-2 minutes.

Step 3: Chill the Mixture. Pour the mixture into a shallow baking dish. Place in the freezer for 1 hour.

Step 4: Scrape to Form Granita. After 1 hour, scrape mixture with a fork and return to the freezer, scraping every 30 minutes for 2-3 hours.

Step 5: Serve and Enjoy. Once fluffy, scoop into bowls and serve, optionally over vanilla ice cream.
