The sauce that made my jian bing taste like the street cart is this one – an all-purpose sauce, and this home cook’s version is the not-spicy one that I keep in the fridge. A home cook wrote it in seven steps with the ratio in the name: three pastes, sugar, and the low-and-slow stir. I made it as written, and it is the sauce that turns flatbread, noodles, and eggs into something memorable.
Wan neng jiang (万能酱) is the all-purpose sauce – onion and garlic cooked with yellow bean paste, tomato paste, and doubanjiang, sweetened with sugar into the savory-sweet spread for jian bing and more. The original is a 7-step recipe with the low-heat stir as its craft.
What Is This All-Purpose Sauce?
This is the sauce you brush on jian bing – the Chinese breakfast crepe – and reach for on noodles, rice, and eggs: finely minced onion and garlic fried until golden, three bean pastes stirred in until the oil runs red, sugar for the sweet note, and water to loosen it into a spread. The home cook’s version is deliberately not spicy – the chili flakes are optional, added to your taste.
The method is the low-and-slow stir. The aromatics soften first, the pastes fry until fragrant, and the sauce simmers until it darkens and thickens. The recipe’s second-batch note is the honest one: the first batch taught it more oil – the sauce stays moist to the last spoon.
For the sauce-driven stir-fry side of the same pantry, my fish-fragrant pork builds a similar paste sauce into a weeknight plate.

Why This Version Works
- The three pastes. Yellow bean, tomato, and doubanjiang – the layered savory-sweet base.
- Golden aromatics. The onion and garlic fried until fragrant – the sauce’s depth.
- Mild by design. No chili unless you want it – the recipe’s not-spicy promise.
- Low and slow. The pastes fry into the oil without burning.
- One jar, everything. Jian bing, noodles, eggs – the all-purpose promise.
Equipment Needed
- A small saucepan or wok
- A garlic press or mini chopper
- A jar for storage
Ingredients
- 100 g (3.5 oz) onion
- 60 g (2 oz) garlic
- 30 g (2 tbsp) sugar
- 60 g (4 tbsp) yellow bean paste (huang dou jiang)
- 50 g (3.5 tbsp) tomato paste
- 50 g (3.5 tbsp) doubanjiang (fermented broad bean paste)
- 3 g (1 tsp) five-spice powder
- 100 ml (1/3 cup plus) water
- Oil for the pan, white sesame seeds and pepper to finish (optional)
Ingredient Notes
Yellow bean paste: The savory backbone. My fish-fragrant pork uses the same paste family.
Doubanjiang: The fermented depth – mild here, since the recipe skips the chili. My dry-fried green beans show its bolder side.
Tomato paste: The bright, sweet tang that balances the salty pastes.
Prep & Mise en Place
Mince the onion and garlic; measure the three pastes; mix the five-spice into the water.
The sequence: soften the aromatics in oil, add the pastes and fry until the oil runs red, stir in the sugar and water, simmer low until glossy, finish with sesame and pepper.

Common Mistakes When Making This Sauce
1. A burnt, bitter paste. Cause: high heat. Fix: low and slow – the red oil needs patience.
2. A dry, stiff sauce. Cause: too little oil. Fix: the recipe’s second-batch lesson – more oil.
3. A one-note sauce. Cause: skipping a paste. Fix: all three – the layers are the flavor.
4. A grainy texture. Cause: chunky aromatics. Fix: mince fine.
5. A raw paste taste. Cause: not frying long enough. Fix: the 3 minutes until fragrant.
6. A scorched pan. Cause: no stirring. Fix: stir constantly on the low heat.
Variations
Spicy: Add chili flakes with the pastes – the recipe’s own option. My fish-fragrant pork shows the chili-forward side.
Thinner: More water for a noodle-sauce consistency.
Smokier: A pinch of smoked paprika in the finish.
The sauce shelf: With fish-fragrant pork and dry-fried green beans, the paste drawer is complete.

I am Lin, a professional Chinese chef and food writer with a decade in restaurant kitchens before turning to recipes. This xiachufang cook’s all-purpose sauce is the jar I keep for jian bing mornings, and the recipe’s oil lesson is exactly why the second batch is the keeper. I tested it as written. I have not tested the spicy variation, so that is your experiment, not my claim.
