Brinjal Moju (Wambatu Moju) is more than just a side dish; it is the crowning glory of a Sri Lankan celebratory feast. This dish is a masterclass in flavor balancing—a deep-fried eggplant pickle that hits every note: sweetness from sugar, sharpness from vinegar, heat from green chilies, and a rich, earthy umami.
When made correctly, the eggplant becomes a "dark jewel," glossy and syrupy, capable of elevating a simple plate of rice into a gourmet experience.
1. The Preparation (The Foundation) To get that signature texture, slice your eggplants into uniform sticks (like chunky fries). Toss them in turmeric and salt, but here is the vital part: let them sit for 10 minutes, then squeeze the water out. This prevents them from absorbing too much oil.
2. The Fry (The Transformation) Heat your oil until it’s shimmering. Fry the eggplant in batches until they are a deep, chocolatey brown. They should look almost burnt but smell fragrant. This concentrated "char" is where the flavor lives.
3. The Dressing (The Soul) While the eggplant drains, create your pickling liquid. Grind mustard seeds into a paste using vinegar instead of water. Whisk this with sugar, chili flakes, and a hint of salt until it forms a thick, tangy syrup.
4. The Marriage In a clay pot or heavy pan, lightly sauté shallots, whole green chilies, and sprigs of curry leaves. Pour in your mustard-vinegar syrup and let it bubble. Finally, fold in the fried eggplant. Turn off the heat and let the eggplant soak up the liquid like a sponge.
Wait for the Magic: Moju is an "aging" dish. It tastes good warm, but it tastes spectacular 24 hours later. The acidity mellows, and the sugar caramelizes further.
The Gloss Factor: If your Moju looks dull, you haven't used enough sugar or oil. The final result should have a mirror-like sheen that catches the light.
Balance the Acid: If it tastes too sharp, add a teaspoon of honey or extra sugar. If it’s too sweet, a splash of lime juice at the very end will brighten the entire dish
The Air Fryer Hack: If you want to skip the deep-frying, toss the eggplant sticks in a generous amount of oil and air-fry at 200°C (400°F) for 15-20 minutes, shaking halfway through. You get the same dark color with 80% less oil.
Mustard Cheat: Can’t find whole mustard seeds? Use a tablespoon of Dijon mustard or English mustard paste. It provides that necessary "kick" without the effort of grinding.
The "Instant" Pickle: Use fried shallots (the kind sold in jars at Asian grocers) and bottled ginger-garlic paste to cut your prep time down to 10 minutes.
