Soak blackbeans in rice wine to puff them up!
Velvet the chicken by marinating in soy sauce, corn flour, rice wine, pepper, egg whites and just before cooking, marinate at least 30 minutes, add in 2 tablespoon of oil to separate the chicken then fry in pan with no oil. Remove chicken after they changed colour and 80% cooked.
In a clean wok add a bit of oil - fry in order, garlic, ginger, onions, blackbeans (keep the marinate for later), chillies, bell peppers, give a good stir, add back in the chicken pieces and 1/2 glass of water.
You may like to thicken the sauce with a bit of corn starch slurry.
Bring to boil and serve - please do not overcook the veggies.p/s I added half cup of sherry just before serving and a big drizzle of Sesame oil
