Why it works: Carrot and turnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sauce as it cooks with the stock, giving it body.
- Brown stock
- Provides the liquid base and most of the sauce's savoury flavour.
- Clarified dripping
- Carries the frying of the vegetables and adds richness to the sauce.
- Onion
- Browns during frying to build colour and deep savoury flavour.
- Tomatoes
- Add acidity and body that balance the richness of the sauce.
- Sherry or madeira
- Adds aroma and a sweet, wine-based depth to the finished sauce.
The step that matters
Stir continually until boiling. Flour settles and scorches on the bottom of the pan if left still, and the sauce can lump or taste burnt. Constant stirring keeps the flour dispersed so it thickens smoothly as the stock heats.
