Homemade Jackfruit Jam
A smooth golden tropical jam that captures the honeyed aroma of ripe jackfruit with a clean lemon finish.
Behind the plate
Ripe jackfruit has a naturally dense, fibrous flesh and a distinctive tropical fragrance. Blending the bulbs before cooking produces a uniform pulp that can reduce into a smooth, rich spread.
Because the mixture is thick from the beginning, it needs attentive stirring and a heavy pan. This formula is presented for refrigerated storage rather than as a tested shelf-stable canning recipe.
Why this recipe works
Puréeing breaks down the jackfruit fibres before sugar is introduced, giving the jam an even texture. Lemon balances the fruit’s honeyed sweetness, while slow reduction develops body without scorching the natural sugars.
The recipe
Ingredients
- 1 kg ripe jackfruit bulbs, seeds removed and flesh chopped
- 700 g granulated sugar
- 2 tbsp fresh lemon juice
Method
- Wash the jars and lids thoroughly and keep the jars warm. Unless using a separately tested canning method, the finished jam must be refrigerated.
- Check that every hard jackfruit seed and its surrounding membrane has been removed, then blend the ripe flesh into a smooth pulp.
- Transfer the pulp to a wide, heavy-based saucepan and add the sugar. Cook over medium-low heat, stirring until the sugar has dissolved.
- Continue cooking with frequent, thorough stirring, scraping the base and corners so the dense fruit does not stick or burn.
- Add the lemon juice and cook for 30–35 minutes, until the jam is thick, glossy and holds a clear track briefly when the spoon passes through it.
- Remove from the heat and carefully fill the warm jars. Wipe the rims, close with clean lids, cool and refrigerate.
Chef’s notes
- Use only ripe, sweet jackfruit flesh. Unripe cooking jackfruit will not give the intended flavour or texture.
- A heatproof spatula with a flat edge is useful for keeping the whole base of the pan clean as the jam thickens.
- If the purée is extremely dense, lower the heat rather than adding unmeasured water, which can extend cooking and dilute the flavour.
- This exact formula has not been presented with a tested water-bath process, so a sealed lid alone should not be treated as proof of shelf stability.
- Keep refrigerated and use within 3 weeks. Discard if mould, fermentation, leakage or an unusual odour develops.
