This guava jam recipe comes from the Rotuma recipe archive at the University of Hawai’i and gives the site a practical Pacific preserving recipe, not just another dessert. It keeps the preserve rooted in island fruit seasons and the way families stock up when guavas are plentiful.

Ingredients
- 8 cups ripe guavas
- 4 cups brown sugar
- 1 cup lemon juice

Instructions

- Boil until the guava is soft and pulpy, then measure the fruit mixture.

- Boil the mixture, stirring regularly, until a little dropped on a wet saucer begins to gel.
- Pour the hot jam into sterilized jars and seal tightly.
Helpful Tips
- Do not overcook the jam or it can set too hard once cool.
- Using very ripe yellow guavas gives the best flavor and color.
FAQ
Do you keep the guava seeds in the jam?
No. In the Rotuma method, the outer skin and seeds are removed before the jam is cooked.
Why add lemon juice?
Lemon juice helps the jam set and balances the sweetness of the fruit.
