Fried aubergine in a sweet, sour and spiced vinegar pickle with mustard seeds and curry leaves — Sri Lanka's most addictive condiment and side dish.
Wambatu moju is one of Sri Lanka's most essential side dishes: aubergine cut into thick batons, deep-fried until tender and slightly crispy, then bathed in a tangy, sweet-sour sauce of vinegar, sugar, mustard seeds, dried chillies and curry leaves. The pickle sits for several hours before serving, allowing the aubergine to absorb the pickling liquid and the flavours to meld into something complex and deeply satisfying. It is served alongside rice and curry — specifically hoppers, pittu or plain rice — and the contrast between the sweet-sour pickle, the coconut-rich curries and the plain rice is one of the defining flavour combinations of Sri Lankan cuisine. A good wambatu moju can transform the most ordinary rice meal into something memorable.
Serves 6
Toss aubergine batons with turmeric and salt. Deep-fry in batches at 180°C until golden and cooked through, about 4–5 minutes. Drain on paper towels.
Heat oil in a pan. Fry mustard seeds until they pop. Add curry leaves and dried chillies. Add garlic and onion, fry until golden, about 8 minutes.
Add vinegar and sugar to the pan. Stir and cook for 2 minutes until slightly syrupy. Add the fried aubergine and toss gently to coat.
Leave the moju to rest for at least 1 hour before serving, or overnight — the flavours improve dramatically. Serve at room temperature alongside rice and curries.
The resting time is essential — serve wambatu moju the same day you make it at the earliest.
Do not over-fry the aubergine — it should be cooked through but not collapsed.
Use good white wine vinegar for a cleaner pickle flavour.
Taste and adjust salt at the very end — flavors concentrate as liquids reduce, and a final pinch of flaky salt sharpens the whole dish.
Karawila moju uses bitter melon (karela) instead of aubergine — sharper and more bitter.
Breadfruit moju is a popular variation with the same pickling technique.
Vegetarian: swap the protein for roasted king oyster mushrooms, smoked tofu or cooked chickpeas — adjust seasoning slightly upward to compensate.
Spicier: add a finely chopped fresh chile or a teaspoon of crushed Aleppo/Urfa pepper to the aromatics for warm, layered heat instead of a single sharp hit.
Refrigerate for up to 5 days — it improves over time. Serve at room temperature.
Moju (pickle/relish) is a fundamental component of Sri Lankan cuisine, influenced by the island's centuries of trade with Arab, Indian and European merchants who brought pickling techniques. Wambatu (aubergine) moju is one of the most beloved versions, and variations of sweet-sour aubergine pickle appear across South and Southeast Asian cuisines, reflecting shared culinary lineages.
You can roast the aubergine at 200°C with oil until golden, about 25 minutes. The texture will be slightly different (softer, less chewy) but the overall dish is still very good.
Yes — most of the components can be prepared up to a day in advance and refrigerated separately. Reheat gently and assemble just before serving so textures stay distinct.
Stay close to the role each ingredient plays: swap aromatics for similar ones (shallot for onion, lime for lemon), and keep the fat-acid-salt balance intact. Spice blends can usually be approximated with what's in the cupboard.
Authenticity sits on a spectrum — what matters more is honoring the technique and balance of flavors. If the dish tastes harmonious and respects how cooks in its home region would build it, you're on solid ground.
