This is a Eurasian dish that brings the influence from Portuguese colonisation of Malacca. As the name suggests "devil" means it's super spicy hot but there is the touch of vinegar from the Portuguese.
Season chicken with salt and set aside. Blend all spice ingredients until fine.
Heat a little oil in pot and lightly brown the sliced shallots and garlic. Add the spice blend and fry until fragrant. Then slightly crush the mustard seeds and add to the pot, blending the ingredients and fry for another 3 minutes.
Put in the chicken pieces and mix well. Add water and cook over medium heat until the chicken is tender.
Add quartered potatoes, onions, tomatoes, vinegar, soya sauce, fresh chillies and season with salt. Cook until the potatoes and chicken are cooked through.
