Thathi’s Lamb Curry
Thathi’s lamb curry — built on patience and low heat, with clarified butter, fresh herbs, warm spices, and thick coconut milk. A thick, deeply fragrant gravy that clings. There are no shortcuts worth taking.
This is Thathi’s lamb curry — the one that has been made in this family for as long as any of us can remember. The method is precise about one thing: patience on low heat. The onions, herbs, garlic and ginger go in first, browning very lightly in clarified butter, absorbing fat and flavour before anything else is added. The spices come next, then the lamb, then the coconut milk — each layer building on the last. What comes out is a thick, deeply fragrant, almost impossibly rich curry with a gravy that clings. There are no shortcuts here worth taking.
- 3 tbsp clarified butter (ghee)
- 1½ large onions (about 250g), chopped very fine into small pieces
- 6 cloves garlic, chopped very fine
- 4 cm piece fresh ginger, chopped very fine
- 12 fresh curry leaves
- 2 stalks lemongrass, bruised and cut very fine
- 3 pieces pandanis (rampe / pandan leaf), cut very fine
- 1½ tsp chilly powder (or to taste)
- 2 tsp ground coriander
- 1 tsp ground cumin
- 1 tsp paprika (more for colour, added at the end)
- ½ tsp garlic powder to taste — optional if you love garlic
- 1½ tsp salt (to taste)
- 1 kg lamb loin or leg, cut into small pieces with a small proportion of fat left in
- 400 ml thick coconut milk (1 can — have a little extra to hand)
- Heavy-bottomed pan with a lid
- Two large spoons or ladles (this is important — see Step 1)

Start low and slow — aromatics first
Melt the clarified butter in a heavy-bottomed pan on LOW heat. Add the onions, curry leaves, lemongrass, pandanis, garlic, and ginger. Using two spoons or ladles, sauté for 8–10 minutes on low, turning and tossing constantly. The goal is a very light browning — not caramelising, not catching. Keep the fat liquid throughout; if it’s disappearing, your heat is too high.
The two-spoon technique Thathi specifies is not optional. It keeps the fat coating everything, prevents sticking, and means nothing scorches on the bottom. Think of it as continuous, attentive stirring rather than occasional checking.

Add the spices
Add the chilly powder, coriander, cumin, paprika, garlic powder, and salt. Continue the same low-heat sauté for 5 more minutes, working the spices into the aromatics with the spoons until every ingredient is coated and glistening. The kitchen will smell extraordinary at this point.
-
Add the lamb
Add the lamb pieces and stir everything together with the ladles for about 8 minutes, increasing the heat just slightly — not high, just a notch up from low. Keep turning and folding so the lamb is well coated and the flavours absorb into the meat. The lamb will release some liquid; continue until this is mostly reduced and the meat looks well seasoned.
-
Add the coconut milk and finish
Pour in the thick coconut milk. Reduce to LOW heat and cook uncovered, stirring occasionally, until a thick gravy begins to form. Then cover with a lid and continue cooking until the lamb is completely tender — typically another 30–35 minutes, depending on the cut.
Check the gravy level as it cooks. The curry should never dry out; if it looks tight, add a splash more coconut milk. You want a thick, rich, clinging gravy — not a broth, and not a paste. Adjust paprika and chilly at this stage if you want more colour or heat.
The fat content in the lamb matters. A completely lean cut will be dry; you want pieces that have a little marbling or an occasional nugget of fat worked in. This is what Thathi means by “a small proportion of fat included.”
-
Rest and serve
Turn off the heat and let the curry rest for 5 minutes before serving — the flavours settle and the gravy thickens just a little more. Serve with steamed white rice or Sri Lankan bread, with a sambol alongside if you have one. This curry improves overnight; the day-two version is arguably better.
This recipe is Thathi’s — written in his hand, in the way he described it to himself, without the kind of measured-out exactness that a recipe usually requires. The quantities here are our best reconstruction. The method is his, preserved as closely as we could.
