Curry debal or Devil's curry is a very spicy traditional stew originating from Malacca (Melaka) in Malaysia. This specialty of the Kristang people is usually made with a combination of chicken, potatoes, white vinegar, salt, sugar, mustard seeds, and oil.
The mustard seeds are tempered in oil, then mixed with a spice paste consisting of garlic, ginger, galangal, turmeric, lemongrass, shallots, oil, and red chili peppers. The chicken is added to the pot and it's coated with the spice paste. The potatoes, sugar, and salt are added to the pot and the stew is covered with water and white vinegar.
