Step‑by‑Step Instructions for Tongan Watermelon Drink
Step 1: Prepare the Base
In a large mixing bowl, start by combining 4 cups of shredded seedless watermelon, 1 cup of canned crushed pineapple (with juice), and 1 cup of shredded fresh coconut. Use a fork or grater to shred the watermelon into fine pieces, ensuring they are juicy and vibrant. This chunky mixture will serve as the refreshing foundation for your Tongan Watermelon Drink.

Gradually add 2 to 3 cups of water to the bowl, mixing as you pour.
