Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 29,030 recipes mention both. Both carry furaneol, which smells caramel, strawberry. The science ↓
The recipe
Ingredients
Contains: wheat, peanut, soy, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
- Sauce
Directions
Prepare the filling
Put the pork and the washed, drained bean sprouts into a bowl.
Cut soaked vermicelli into 5 cm (2 in) lengths.
Soak dried mushrooms in hot water for 25 minutes.
Discard stems and slice mushroom caps finely.
Combine all these ingredients with the onion, sugar, soy sauce and fish sauce, mixing thoroughly.
Shape and fry the rolls
If using small sheets, 125 mm (5 in) square, use one sheet per roll.
If using large sheets 250 mm (10 in) square, cut in half.
Take 2 teaspoons of the mixture and shape into a neat roll.
Place at one end of the pastry square and roll up, turning ends in so the filling is completely enclosed.
Deep fry in hot oil over medium heat, cooking the rolls for at least 2 minutes on each side so the filling is thoroughly cooked.
Drain on paper towels and serve warm, accompanied by the dipping sauce.
Make the dipping sauce
Crush the garlic with some of the sugar.
Combine with the chilli and fish sauce, leave for 10 minutes.
Add the boiling water, lemon juice and vinegar and leave in a warm place for 30 minutes for flavours to mellow.
Stir in the peanuts just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork
- Provides the savoury, meaty body of the filling.
- Bean thread vermicelli
- Adds a soft, chewy texture that binds the filling.
- Spring roll pastry
- Forms a crisp, golden shell when deep fried.
- Fish sauce
- Adds salty, savoury depth to both the filling and the sauce.
- Lemon juice
- Adds acidity that brightens the dipping sauce.
- Sugar
- Balances the saltiness and acidity with sweetness.
The step that matters
Deep frying the rolls. The filling is raw pork, so the rolls must fry long enough for the centre to cook through. Keeping the oil hot and cooking each side fully prevents greasy, undercooked rolls with a pale, soft shell.

Fit is the average pairing score against pork, mushroom, onion, sugar, sauce, fish sauce, garlic. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
