Mature Kamansi Seeds: Boil, Peel and Pan-Brown Breadnut for a Rice Side

Kamansi, also known as breadnut, has two kitchen identities: the immature fruit can be cooked as a vegetable, while mature fruit bears edible, chestnut-like seeds. Treating the mature seeds as though they were young fruit makes an unhelpful mush; treating them like ready-to-eat roasted peanuts skips their cooking requirements. A more useful small-batch method is to boil the separated mature seeds until the centre is soft, peel away the inedible coverings and brown the cooked kernels briefly with garlic. Source 2

Know the ingredient

Kamansi is breadnut, Artocarpus camansi. Its young fruit is cooked as a vegetable, while mature fruit supplies edible seeds. The National Parks Development Committee describes the seeds as chestnut-like; that comparison concerns appearance and use, not botanical identity or a guarantee for someone with a food allergy. Buy mature seeds sold for cooking, separate from seeded jackfruit or a decorative tree fruit. Source 2

Ingredients and equipment

For a small side dish, use 350–400 g mature food-grade kamansi seeds, enough water to cover them by 3 cm, two sliced garlic cloves, 1 tbsp oil and salt to taste. Have a saucepan, colander and a small knife. Calamansi is optional at serving; the purchase weight includes the seed coats you will remove.

How to prepare it

1. Rinse the seeds and discard mouldy, damaged or doubtful pieces. Put them in a saucepan with fresh water covering them by about 3 cm.
2. Bring to a boil, then simmer gently. Begin checking a large seed after 20 minutes and continue as needed until its centre is soft enough to mash; seed size and maturity change the timing.
3. Drain and let the seeds cool just enough to handle safely. Peel off the firm outer coats and any tough membrane.
4. Cut one of the largest peeled seeds. If the middle is hard, return the peeled seeds to simmering water until tender before frying.
5. Warm the oil and garlic in a pan over medium-low heat. Remove the garlic when lightly golden, then add the well-drained seeds and turn for about 5–8 minutes until lightly browned.
6. Return the garlic, season and serve warm. Break larger seeds into bite-sized pieces, and offer calamansi separately.

What success looks like

The inside should be soft and starchy, with a lightly browned exterior. Hard centres need further moist cooking. If the outside browns too quickly, lower the heat; if seeds steam instead of browning, drain them more thoroughly and use a less crowded pan.

• Kernel is chalky or hard: Seed was not boiled sufficiently. Return to boiling water until genuinely tender.
• Kernels crumble in the pan: They were overcooked or stirred roughly. Brown briefly with broad pan movements.
• High purchase weight, poor yield: Heavy seed coats and unsuitable fruit. Cost the peeled edible weight, not the original fruit.

Substitutions and value

Compare the purchase price with the weight of peeled cooked kernels. Seed coats and damaged pieces do not reach the plate. Boiled chestnuts or cooked beans can fill a similar place in a meal, but they have different flavours and allergen considerations.

Handling and storage

Use mature seeds sold for food and cook them before eating. Do not identify a wild fruit from a photograph alone. Allow hot seeds to cool enough for peeling, and use a stable board rather than holding them against the knife. Refrigerate leftovers in shallow containers within two hours, or within one hour when the surroundings are above 32°C. Keep the refrigerator at 4°C or colder. Source 1
