Why it works: Onion and mustard match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 9,259 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Prepare
Cut the cold boiled beef into ¼ inch thick slices, trimming off fat and dry parts.
Peel and finely shred the onions, then fry them in butter until light brown.
Make the sauce
Sprinkle flour over the onions, season with salt and pepper, and let simmer for 5 minutes.
Add the broth and stir well, cooking for 15 minutes.
Stir in the mustard, then add the beef slices, warming them without boiling for a few minutes.
Adjust seasoning if needed, then serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Boiled beef
- Forms the main body of the dish, providing the meat that is warmed through in the sauce.
- Onions
- Soften and brown in butter, adding sweetness and depth to the sauce.
- Butter
- Carries the frying of the onions and adds richness and flavor.
- Flour
- Thickens the broth into a smooth sauce as it cooks with the onions.
- Broth
- Forms the liquid base of the sauce, carrying the flavor of the dish.
- Mixed mustard
- Adds a sharp, tangy bite that cuts through the richness of the sauce.
The step that matters
Warming the beef without boiling. Boiling the sliced beef in the sauce toughens the meat fibres and can make it dry and stringy. Keeping the sauce just below a boil warms the slices gently and keeps them tender.
