Bogobe is porridge, the staple of Botswana, made by stirring , maize or meal into boiling water. Bogobe jwa lerotse is its festive form and a national dish: porridge cooked with lerotse, a local melon, and finished with madila, the thick sour milk of the Tswana table. It is a dish for weddings and big gatherings, where it shares the table with seswaa, the pounded salted meat that is Botswana's other celebration dish.
Lerotse looks like a small watermelon but has orange flesh and is far less sweet, closer to cucumber when raw. Cooked down it gives the porridge a delicate, faintly fruity flavour. The melon is boiled in batches until it collapses and can be beaten smooth with a lehetho, a wooden whisk, then the meal is whisked in and cooked to a soft porridge, and the sour milk goes in at the end.
Outside Botswana lerotse is hard to find, so this recipe suggests a firm, barely ripe melon instead. The porridge will be a little sweeter, but the method is the same.

Metric
Serves 6
- 1/2 melon (about 1.5 kg) lerotse (cooking melon), peeled, seeded and cut into 3 cm chunksHard to find? about 1.5 kg firm, barely ripe cantaloupe or winter melon - cantaloupe is sweeter and winter melon blander than lerotse; neither tastes quite the same
- about 3 cups (720 ml) water, plus more as needed
- 2 cups (about 300 g) meal (mabele)
- 3/4 cup (180 ml) sour milk (madila) or plain buttermilk
- a pinch salt, optional
- 1 to 2 tsp sugar, optional
Instructions
- 1Bring the water to the boil in a heavy pot, about a quarter full. Add as much melon as fits, cover and cook; as it softens and shrinks, add the rest in batches.
- 2Cook gently, covered, for about 30 minutes, until the melon has completely collapsed and can be whisked into a smooth pulp with a wooden whisk or a balloon whisk.
- 3Sprinkle in the sorghum meal a little at a time, whisking constantly to break up any lumps, until it is all in and the mixture is a thick, creamy porridge. Add a splash of boiling water if it gets too stiff.✎ Chef’s noteAdd the meal slowly and whisk as you go. Lumps are much easier to prevent than to beat out later.
- 4Cover and simmer over low heat for about 15 minutes, stirring now and then with a wooden spoon, until the sorghum is cooked and no longer tastes raw.
- 5Gently fold in the sour milk, and the salt and sugar if using, then simmer for another 5 minutes. Serve warm.

📍
Gaborone. The kitchen follows the cattle. This is dry grazing country, so beef is the meat that matters and the grains are sorghum and maize rather than anything thirstier, while the greens arrive as morogo, wild leaves gathered off the veld and cooked down, rather than out of a market garden.
🗺️
Botswana. The porridge underneath is bogobe, made from sorghum, and ting is its soured version, left to ferment before cooking. Morogo, the wild greens gathered rather than planted, goes alongside. Cattle are not a picture here but an export industry, which is what puts beef on ordinary plates in a country that is mostly Kalahari.
🌍
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.
