Why it works: Sorrel and beetroot share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and cooks put them together in 64 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
- Spinach
- Wilts into a soft, moist filling that spreads easily over the bread.
- Sorrel
- Adds a sharp, sour edge that balances the richness of the butter or sauce.
- Beetroot
- Its leaves and stalks cook down into a tender, earthy-flavoured filling.
- Fried bread or toast
- Gives a crisp base that holds the warm filling in place.
- Butter
- Adds richness and helps moisten the greens as they heat.
- Plain white sauce or soubzse sauce
- Moistens the greens and adds creaminess and body to the filling.
The step that matters
Spread the mixture on hot fried bread immediately.. Hot filling keeps the greens warm and fluid enough to spread, while fried bread soaks up moisture quickly and turns soggy if the wet mixture sits on it.
Swap the beetroot
How well each one fits the dish's main ingredients (spinach, sorrel, bread, butter, sauce, pepper):
