Ngai ngai is a sour-leaf stew of the Republic of the Congo and its neighbour across the river, built from the leaves of the roselle plant, a relative of hibiscus. Its name is Lingala for "sour sour", and that pucker is the whole point: the leaves cook down into a soft, tangy, deep-green sauce.
The leaves are simmered with onion, tomato, garlic, ginger, and chili, enriched with red , and most often served with fried freshwater fish, though a purely vegetable version eaten with is just as at home on Congolese tables.
Sour, rich, and earthy, ngai ngai is an everyday sauce, spooned over or alongside fried fish and mopped up with , chikwangue, rice, or . It is not to be confused with the sweet hibiscus-flower drink (bissap); here it is the sour leaf that does the work.

Ingredients
US
Metric
Serves 4
1 lb roselle/sorrel leaves (ngai ngai), fresh or frozen, chopped
Hard to find? 1 lb spinach with a good squeeze of lemon, or garden sorrel if you can get it - the name means sour sour, so whatever you use has to be sharp; frozen roselle leaves from an African grocer are far closer than anything you will find fresh in a supermarket
1 lb fried fish (tilapia or mackerel), to serve
1 onion, chopped
1 tomato, chopped
3 cloves garlic, minced
1 tbsp fresh ginger, grated
1 hot chili ( or pili-pili)
1/4 cup red
to taste salt or bouillon
Instructions
1
If using fresh sorrel leaves, strip them from the stems, wash, and blanch briefly in hot water until they change colour; drain and chop (frozen leaves just need thawing).
2
Season and fry the fish until golden on both sides; set aside. (For the vegetable version, skip the fish and serve with boiled plantains.)
3
Warm the palm oil and soften the onion, then add the garlic, ginger, and chili, followed by the tomato, and cook down to a sauce.
4
Add the sorrel leaves with a little water and simmer about 20 minutes until soft and melded, seasoning with salt or bouillon.
✎ Chef’s note
The leaves are meant to turn very soft and sour; give them the full simmer so the sharpness mellows into the palm oil.
5
Nestle the fried fish into the sour stew (or serve it alongside) and eat with fufu, chikwangue, rice, or plantain.
Brazzaville home tradition.

Brazzaville. Cassava carries the meal in three separate forms. The root is milled into flour for fufu, fermented and steamed into chikwangue, and the leaves are pounded and cooked down separately with palm oil. Plantain and groundnut sauces fill out a plate that changes very little from house to house.

Republic of the Congo. Saka-saka, pondu and mpondu are three names for the same cassava-leaf dish, pounded fine and simmered long with palm oil. Chikwangue is the other cassava form, fermented and steamed into a firm loaf that keeps and travels, which matters on a river where the market may be a day away.
🌍
Africa. Much of what reads as timeless African cooking is younger than the Atlantic crossings. Maize, cassava, groundnut, chilli and tomato all arrived from the Americas after 1500 and pushed older crops aside; millet, sorghum, teff, yam and fonio are the ones that were already here, and the map still shows the join.
The story behind this dish is up top, worth a read while the pot works.

Storing it: Stews and braises keep 3 to 4 days refrigerated and often taste better the next day. Reheat gently, adding a splash of water if it has thickened.
