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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tripe
- Forms the main body of the stew and gives it a tender, chewy texture.
- Butter
- Adds fat for richness and carries flavour through the base.
- Flour
- Thickens the sauce once it is cooked in the butter and combined with liquid.
- Onion
- Adds aroma and gentle sweetness as it fries and browns.
- Reserved tripe cooking water
- Provides the liquid that forms the body of the sauce and adds moisture.
- Fluid beef
- Adds savoury, meaty depth to the sauce.
The step that matters
Frying the onion and flour until brown. Cooking flour in fat until browned removes its raw taste and gives the sauce a nutty colour and flavour. Underdone flour leaves a pasty taste, while overbrowned flour turns bitter and can burn, so watch the colour closely.
