Clean the chillies, cut lengthwise, remove seeds and wash. Chop red and green chillies separately. Peel garlic and chop finely. Crush the green chillies and garlic finely in a mortar or puree them in a mixer.
Clean, wash and cut the peppers into strips. Peel shallots and cut them into fine slices. Dab meat dry and cut into thin slices. Heat the oil in a wok or large frying pan.
Fry the chili mixture for about 1 minute. Add the meat and stir-fry for another 1 minute. Take out. Fry the peppers and shallots in the frying oil for 2-3 minutes. Stir in red chillies, seasoning sauces and sugar.
Fry for another 1-2 minutes. Wash the basil, shake dry and pluck the leaves. Fold in basil and meat. Basmati rice tastes good with it.
