The scent of grilled corn coming along with chilly winds of winter nights always brings about a bit of warmth inside many Hanoians.
Vendors, who are mainly middle-aged and old women, begin to cook and sell grilled corn from late afternoon.
They often put corns on fire built by charcoal and constantly turn them over to make corns become well cooked but not burnt.
As a result, while the cover becomes hard and browned, the inside is still glutinous, sweet and packed with flavors.
Grilled corn stalls can be found almost anywhere on the sidewalk of Hanoi during the night.
