Use ripe, juicy watermelon for the best natural sweetness and fresh fruit flavor.

Measure exactly 1 cup of strained watermelon juice to maintain the proper gelatin-to-liquid ratio.

Avoid boiling the gelatin mixture because excessive heat can interfere with its setting properties.

For extra sour gummies, gradually increase the citric acid in the coating according to taste.

For strawberry watermelon gummies, replace part of the watermelon with fresh strawberries, keeping the total strained juice at 1 cup.

For a naturally sweetened variation, omit the granulated sugar and citric acid coating.

For tropical gummies, replace a small portion of the watermelon juice with mango or pineapple juice while maintaining the same total liquid measurement. Fresh pineapple contains enzymes that can prevent gelatin from setting, so use heat-treated pineapple juice.

For a stronger lime flavor, replace some of the lemon juice with additional fresh lime juice.

Store uncoated gummies in an airtight container in the refrigerator for up to 5 days. Separate layers with parchment paper to prevent sticking.

Add the sugar and citric acid coating immediately before serving to prevent it from dissolving and becoming sticky.

Freezing is not recommended because thawing can make the gummies watery or sticky.

Serve chilled for the best chewy texture and refreshing flavor. Reheating is not necessary.

Gelatin is not vegetarian. Agar-agar may be used in a separately adapted recipe, but it requires different preparation and produces a firmer texture.

The number of individual gummies depends on the size and shape of the silicone molds.
