Put the cucumber, carrot, and vinegar in a small bowl and set aside. Heat 1 tbsp. oil in a pan and fry the meat in it until golden brown. Take it out, set it aside. Pour the remaining oil into the pan and lower the temperature below. Put the garlic and ginger in the pan, fry for 2 minutes until softened but not browned. Sprinkle with sugar, pour in soy sauce and 150 ml of water, then cook in beads for 5 minutes until slightly thickened. Put the meat back in the pan and heat over the sauce.
