Wash the fish, dab dry and dice. Sprinkle with 2 tablespoons of vinegar and salt. Clean, peel and slice the carrots. Peel onions, cut into rings. Rinse sprouts cold and let them drain.
Turn fish pieces in 2-3 tablespoons of starch and fry in 2 tablespoons of hot oil for 5-8 minutes in portions. Sprinkle with sesame seeds shortly before the end of the frying time. Remove the fish. Heat the remaining oil in the pan.
Brown the carrots and onions in it. Add 4 tablespoons of water and stew for about 10 minutes. Add sprouts and peas after 5 minutes. Take out vegetables. Dissolve roasting mixture with 6 tablespoons of water, ketchup, remaining vinegar and soy sauce and bring to the boil.
Mix 1 tablespoon of starch and 2 tablespoons of water. Thicken the sauce with it. Season to taste with salt, pepper and ginger. Heat the fish and vegetables in the sauce. Rice tastes good with it.
