Why it works: Onion and beef are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Stewed Beef
Ingredients
Directions
Prepare the onions
Peel and slice the onions thinly.
Make the sauce
In a stewpan, melt the butter over low heat and add the onions. Stir until browned but not burnt.
Add the brown flour and mix smoothly.
Moisten with broth or water and add a small piece of glaze.
Stir in the salt, sugar, and pepper.
Finish and serve
Add the thin slices of cold beef and heat through on the back of the stove for five minutes.
Serve on a very hot dish garnished with fried potatoes or croutons.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Browned slowly in butter, they add sweetness and deep savoury flavour to the sauce.
- Brown flour
- Cooked into the butter and onions, it thickens the liquid into a smooth sauce.
- Butter
- Fat that softens and browns the onions and carries flavour through the stew.
- Broth or water
- Liquid that moistens the flour and turns the mixture into a sauce.
- Sugar
- Adds a little sweetness that balances the savoury onions and beef.
The step that matters
Browning the onions. Onions should turn golden without burning. Slow cooking over low heat develops sweetness and colour, while scorched onions taste bitter and spoil the whole sauce.
