- Why is the sauce lumpy?
- Likely you put cornflour in warm water, or poured it too fast into hot sauce. Always mix with cold water and drizzle slowly.
- I don't have rice vinegar, what should I use?
- Cider vinegar is the best substitute because it also has a fruity base note.
- Can I use fresh pineapple?
- Yes, it will be even tastier! But you will still need juice from a carton/tin for sweetness.
Sweet and Sour Chicken Sauce
The star of Chinese buffets, now homemade, without preservatives or flavour enhancers. This sauce is the art of balance: tropical sweetness of pineapple and sharp acidity of rice vinegar form the backbone, deepened by tomato. The result is a shiny, sticky sauce that is phenomenal not just with chicken, but also with crispy fried vegetables or prawns.

Instructions
1
✓
Mix cold water with cornflour in a small bowl until you get a completely smooth, milky liquid. Set aside.
Tip: Cornflour grains do not clump in cold water, but lump immediately in hot (gelatinisation), which is why it must be mixed beforehand.
2
✓
Core the pepper and cut into 2x2 cm cubes. Chop pineapple similarly if needed.
Tip: Uniform size is important not just for aesthetics but heat treatment: they will cook at the same time.
3
✓
In the frying pan, mix tomato puree, pineapple juice, sugar, vinegar, and soy sauce. Bring to a boil over medium heat.
Tip: Soy sauce provides the 'umami' (savoury) base giving depth to the sweet sauce.
4
✓
Drizzle cornflour water into hot sauce in a thin stream while stirring constantly. Cook for 1-2 minutes until it thickens and becomes translucently shiny.
Tip: Cornflour needs to boil to activate thickening power and remove floury aftertaste.
5
✓
Throw in pepper and pineapple. Cook for another 2-3 minutes, just enough to warm through but remain crunchy.
Tip: The essence of Asian cuisine is texture: vegetables should crunch (al dente), not be cooked soft.
6
✓
Serve immediately poured over fried chicken pieces, accompanied by rice.
Tip: The sauce thickens further while cooling.
