Wambatu moju

වම්බටු මෝජු (wambatu moju): crisp-fried aubergine in a sweet, sour and spicy mustard-vinegar pickle with shallots

No wedding buffet or almsgiving lunch in the Colombo suburbs feels complete without a dish of wambatu moju, the dark, glossy aubergine pickle that people go back for long after the curries have run out. Strips of long purple aubergine are coloured with turmeric, fried until they shrink and turn deep gold, then tossed with whole shallots and green chillies in a hot, sweet-and-sour paste of ground mustard seed, vinegar and sugar. It is eaten in small spoonfuls with rice, and it tastes even better a day later, once the flavours have soaked in. The point that trips most cooks up is under-frying the aubergine: pale pieces soak up the vinegar like a sponge and go soggy, so fry until they are properly brown and slightly shrivelled. Chef's tip: grind the mustard seeds with some of the vinegar rather than buying ready-made mustard; the fresh paste gives the pickle its pleasant nose-tingling bite.

Polos curry

Polos is the tiny unripe jackfruit picked in the Western and Sabaragamuwa provinces long before it sweetens, and cooked low and slow it becomes one of the island's most loved festival curries, especially at Sinhala and Tamil New Year in April and at wedding lunches. The firm, pale flesh soaks up a very dark roasted curry powder, garlic, ginger, goraka (a smoky souring fruit) and coconut milk until it turns almost black-brown and tastes rich, sour and meaty. Fresh polos is hard to find abroad; tinned young green jackfruit in brine works well. A frequent mistake is not cooking it long enough, which leaves it squeaky; the pieces must be soft enough to break with a spoon. Chef's tip: oil your hands and knife before cutting fresh jackfruit; the sticky white sap washes off oiled skin but not dry skin.

Mint and onion chutney

Onions fried gently until soft and sweet, then blended with fresh mint, green chilli and lemon juice. It's a mellow, fresh-tasting chutney that is great with bhajias, samosas, kebabs and tikka, or spread in sandwiches.

Vegan nuoc cham

Nước chấm is the dipping sauce that goes with almost everything in Vietnam: spring rolls, bánh xèo, noodle salads and broken rice. Buddhist vegetarian cooks, all over the country, make it without fish sauce, using light soy sauce and a little coconut water for the deep, rounded taste. It should be thin, clear and pale amber, with flecks of garlic and chilli floating on top. Chef's tip: dissolve the sugar in the warm water first, then add the lime and soy, and stir in the garlic and chilli last, pounded with a pinch of sugar, so they float on the surface instead of sinking.
