How to Make Mary Berry Sweet and Sour Chicken
- Prepare the chicken: Place the chicken pieces in a bowl. Season with salt and pepper, then toss in cornflour until evenly coated. Dip each piece into the beaten egg.
- Heat the oil: Pour vegetable oil into a deep frying pan or wok and heat over medium-high until hot but not smoking.
- Fry the chicken: Fry the coated chicken pieces in batches for 4 to 5 minutes until golden and cooked through. Remove and drain on kitchen paper.
- Prepare the sauce: In a bowl, mix ketchup, vinegar, sugar, soy sauce, and pineapple juice until smooth.
- Cook the vegetables: In a clean pan or wok, lightly sauté the peppers and onion for 3 to 4 minutes until just tender but still crisp.
- Add the sauce: Pour the prepared sauce into the pan and bring to a gentle simmer.
- Thicken the sauce: Stir in the cornflour slurry and cook until the sauce thickens to a glossy consistency.
- Combine and finish: Add the fried chicken and pineapple chunks to the sauce. Toss well to coat evenly and heat through for 2 to 3 minutes before serving.

Tips
How do I keep the chicken crispy?
Fry the chicken in small batches and avoid overcrowding the pan. Add it to the sauce just before serving to maintain its texture.
Can I make the sauce less sweet?
Reduce the sugar slightly and add a little extra vinegar or soy sauce to balance the flavours.
What oil is best for frying?
Use a neutral oil such as vegetable or sunflower oil for the best results.
Can I bake the chicken instead of frying?
Yes, bake at 200°C for about 20 minutes, turning halfway, though the texture will be less crisp.
