- 170 g aubergine, chunky pieces
- ⅛ tsp salt
- 1 tbsp cornflour for coating
- 250 g potato, peeled and cut into small chunks

- Sauce: 1½ tbsp light soy sauce and 1 tsp dark soy sauce
- Sauce: ½ tbsp unsalted stock instead of cooking wine

Let’s make it
-
Prepare the vegetables
Salt aubergine and leave for 5 minutes, then coat with the tablespoon of cornflour. Cut potato chunks small enough to cook evenly. Mix sauce ingredients separately.
-
Cook in stages
Heat oil in a wide frying pan. Fry potato over medium heat, turning, until golden and tender right through, then lift out. Cook pepper until lightly blistered and remove. Fry aubergine until golden outside and soft inside. Allow longer if any pieces remain firm.
-
Glaze everything
Leave a thin film of oil in the pan and briefly sizzle garlic and spring onion. Stir the sauce again, add it over low heat and stir as it thickens. Return vegetables and toss until hot and coated. Add a spoonful of water if needed.
-
Serve while glossy
Eat straight away with rice. Separate batches take a little patience, but give each vegetable its own texture.
