Why does my sauce turn out cloudy instead of glossy?

Cloudy sauce usually means the cornflour slurry was added before the sauce was bubbling, or it wasn't stirred immediately. Always add slurry to a hot, bubbling liquid and stir continuously.

Can I prep the sauce mix ahead of time?

Yes, combine ketchup, soy sauce, vinegar, sugar, and spices in a small bowl and refrigerate. Add the cornflour slurry separately just before cooking.

How do I make it less spicy?

Omit the green chili and skip the red chili powder entirely — the dish will still have warmth from ginger and black pepper.

Can I freeze leftovers?

Freezing is not recommended because the vegetables will release water upon thawing, turning mushy. Eat fresh or refrigerate for up to 2 days.

What if I don't have rice vinegar?

Substitute with white vinegar or apple cider vinegar at the same quantity — the tang will be slightly different but still delicious.

Crunchy, vibrant vegetables tossed in a glossy sweet-and-sour sauce with a hint of chili heat. This Indo-Chinese restaurant favorite comes together in one wok in under 25 minutes. The sauce balances tangy vinegar, sweet tomato notes, and savory soy, coating every piece of bell pepper, onion, and carrot beautifully. Perfect alongside fried rice or hakka noodles.

PRO TIPS

What to keep in mind.

7 tips from the recipe — small details that make a real difference to the final dish.

1
Cut all vegetables into uniform 1-inch pieces to ensure even cooking in the high-heat wok.
2
Keep vegetables moving constantly over high flame to retain crunch and avoid steaming.
3
Add the cornflour slurry only after the sauce bubbles to prevent a raw-starch taste.
4
Use a mix of bell pepper colors for a vibrant, restaurant-style presentation.
5
For extra heat, add the green chilies early in the stir-fry step.
6
Make ahead: prep all vegetables and sauce ingredients up to 2 hours in advance and refrigerate.
7
Leftovers reheat best in a hot wok for 30 seconds — avoid the microwave to keep vegetables crisp.
