🌽 Tanzanian Roasted Corn
Mahindi Choma
Tanzanian Mahindi Choma — whole corn cobs roasted slowly over charcoal until the kernels are lightly charred and intensely sweet-smoky, rubbed with lemon and chilli salt. The most universally eaten street snack in Tanzania — found at every bus station, market, roadside, and beach.
Roasted corn is the snack that connects all of Tanzania — from the lakeside villages to Dar es Salaam's busiest intersections, from Zanzibar's beaches to Kilimanjaro's foothills, the charcoal corn vendor is always there. The lemon and chilli salt rubbed on at the end is what makes it Tanzanian — simple, perfect, irreplaceable.
Ingredients
Equipment: Charcoal grill or jiko
- 4 whole corn cobs — husks on or removed
- Coarse salt
- Chilli powder
- 2 lemon halves for rubbing
Method
- If husks on: soak in water 10 minutes. Place directly over coals.
- If husks removed: place directly over medium coals.
- Roast 15—20 minutes, turning every 3—4 minutes.
- The kernels should be lightly charred in places and the cob tender.
- Rub immediately with cut lemon half.
- Sprinkle chilli and salt. Rub in with the lemon.
- Eat immediately.
Chef Tips
- Medium coals — not too hot or the outside chars before the inside cooks.
- The lemon must be rubbed on while piping hot — it penetrates better.
- Charred spots are flavour — do not fear them.
Common Mistakes to Avoid
- Too high heat — burns exterior, raw interior.
- Cold corn before seasoning — lemon does not penetrate.
The Science
Roasting corn in the husk creates a steam environment — moisture trapped by the husk cooks the corn from within while the outside chars slowly. This dual-mode cooking (steam + direct heat) produces more evenly cooked corn than husked roasting. The Maillard reaction on charred kernels creates pyrazines and furans — the intensely flavoured compounds of roasted corn.

Cultural Note
