Vendors roast the cobs unshucked over open coals until the kernels blister and char, then peel the husk back to use as a handle.
Whole corn cobs are grilled over small charcoal braziers until the kernels blister and darken, then sold hot off the coals with a rub of salt or chili. Vendors set up braziers on street corners and near markets throughout Kigali, especially as the maize harvest comes in.
