Chambo

Ingredients

Fish

• 4whole chambo (Lake Malawi tilapia), about 400 g each, scaled and gutted, slashed three times on each side

Marinade

• 3garlic cloves, crushed
• 20 gfresh ginger, grated
• 2 tbsplemon juice
• 1 tspsalt
• 1 tspblack pepper
• 1 tsppaprika
• 1–2bird’s eye chillies, minced
• 2 tbspvegetable oil

To cook

• 3 tbspvegetable oil, for basting or shallow frying
• 1onion, sliced into rings

To serve

• Nsima, hot
• 1lemon, in wedges
• Chopped tomato and onion salad

Directions

1. Rinse the fish inside and out, scraping away any dark membrane in the cavity, and pat dry. Slash the flesh to the bone three times on each side at an angle.
2. Mix all the marinade ingredients and rub it into the slashes and the cavity, working it in with your fingers. Leave 30 minutes at cool room temperature; longer and the lemon starts to cure the flesh.
3. For the grilled version, build a charcoal fire and let it burn down to grey-white embers with a steady, medium heat. You should be able to hold your hand 15 cm above the grate for 4 seconds.
4. Oil the grill bars well and lay the fish on. Grill 8–10 minutes on the first side without moving it; the skin must release by itself before you attempt to turn it.
5. Turn once, using two spatulas, and grill 7–8 minutes on the second side, basting with the oil and the marinade left in the dish.
6. For the fried version, heat 1 cm of oil in a wide pan to 180°C (350°F) and shallow-fry the fish 6–7 minutes a side until the skin is deep brown and crisp and the slashes have opened.
7. The chambo is done when the flesh at the thickest part of the shoulder is opaque and pulls away from the backbone cleanly, and the eye has turned white. About 62°C (145°F) at the bone.
8. Fry the onion rings briefly in the same pan or on a foil tray on the grill, until softened and singed at the edges.
9. Serve the whole fish on a platter with the onions over the top, lemon wedges, a fresh tomato salad and a mound of nsima, eaten with the hands.

Technique

• Chambo refers to a group of endemic Oreochromis species found only in Lake Malawi. Stocks have fallen sharply from overfishing, and much of what is now sold as chambo is farmed or is a different tilapia; buying responsibly matters.
• Slashing to the bone is not decorative. It lets the marinade reach the thick shoulder meat and lets heat penetrate so the fish cooks evenly.
• Do not move the fish on the grill until the skin releases. Forcing it early tears the skin off and leaves it on the bars.
• Malawians generally keep the seasoning simple: salt, lemon and chilli, so the sweet, firm flesh of the fish itself carries the plate.

Substitutions

• Any whole tilapia is the natural substitute; sea bream, red snapper or grey mullet of the same size also work with identical timings.
• No charcoal grill: a very hot ridged griddle pan or a hot oven at 220°C (425°F) for 20 minutes will do, though you lose the smoke.
• Usipa, the tiny dried Lake Malawi sardines, are the everyday alternative when chambo is out of reach.

Variations

• Chambo fried whole in a deep pan, the standard at lakeside restaurants in Cape Maclear.
• Chambo in a light tomato and onion stew, simmered and served over nsima.
• Smoked chambo, cured over green wood on the shore and sold at roadside stalls.
