Why it works: Onion and mushroom are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 10,626 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Sauce for Minced Beef
Ingredients
Directions
Make the sauce
In a stew-pan, combine chopped onions, malt vinegar, and glaze. Boil together for a few minutes.
Add brown sauce and broth; stir quickly over high heat until the sauce coats the back of a spoon.
Stir in chopped mushrooms and gherkins. Season with Nepal pepper, salt, and sugar.
Serve
Serve the sauce separately with minced beef and poached eggs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sauce
- Provides the main body, savoury flavour and colour of the sauce.
- Broth
- Adds liquid and savoury depth, helping the sauce loosen and spread.
- Malt vinegar
- Adds sharp acidity that balances the richness of the brown sauce.
- Chopped gherkins
- Contribute sharp, acidic bite and texture to the finished sauce.
The step that matters
Thickening over high heat. Stirring quickly over high heat helps the sauce reduce and thicken evenly, while preventing it from scorching on the base of the pan. Stop once it coats the back of a spoon, since it thickens further as it cools.
Swap the onion
