Hanna Tran Hanna Tran | Updated October 16, 2026

Mứt cóc chua cay is a jam made from yellow mombin fruit, cooked with sugar, chilli powder and ginger so it ends up a little sweet, sour and spicy. It’s one of the recipes made in the author’s family; her sister-in-law loved it when she was pregnant. It makes a good Tết treat to share when friends visit, and you can add more ginger if you like.

Mứt Cóc Chua Cay Recipe: Sour and Spicy Yellow Mombin Jam

Plan ahead: the fruit soaks for 5–6 hours, sits in sugar for about 4–6 hours, and dries for 2 hours after cooking.

    Ingredients

    • 1 kg yellow mombin fruits (choose the green-skinned ones)
    • 400 g white sugar
    • 1 cooking lime (vôi), from Vietnamese markets
    • 1 small clove ginger
    • 1 teaspoon chilli powder (depending on your taste)

    How to make mứt cóc chua cay

    1. Make the lime water and cut the ginger

    Mix the cooking lime into 3–4 litres of cold water. Wait 15 minutes, then use the water on top and pour away the dregs at the bottom.

    Peel the ginger and cut it into strips.

    Peel the yellow mombin fruits and cut them into halves or quarters. Soak them in the lime water from step 1 for 5–6 hours.
