Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Spinach.
Ingredients
Directions
Prepare the spinach
Pick spinach leaves from the stems and wash them thoroughly in spring water, changing the water several times.
Shake the spinach in a dry cloth or drain it in a large sieve.
Boil well-salted water and add the spinach, pressing it down with a skimmer to ensure even cooking.
Cook for 8 to 10 minutes until tender; check by squeezing a leaf between your fingers.
Drain the spinach and transfer it to fresh water to cool, then form it into balls and squeeze out excess moisture.
Chop the spinach finely on a clean surface.
Make the gravy
Melt ½ cup of butter in a saucepan, add the chopped spinach, and stir over low heat for 10 minutes until dry.
Dredge in 1 tablespoon of flour and mix well.
Gradually add rich veal gravy or boiling cream, stirring until absorbed.
Serve
Serve hot, garnished with small fried bread pieces or puff pastry.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spinach
- Forms the bulk of the dish and gives it its green colour and earthy flavour.
- Butter
- Enriches the spinach and carries flavour while it cooks dry.
- Flour
- Thickens the buttery spinach so the added liquid is held and turns creamy.
- Veal gravy or boiling cream
- Supplies the liquid that is absorbed, giving the dish a rich, smooth moisture.
The step that matters
Stir the spinach dry in butter before adding flour. Excess water left in the spinach dilutes the butter and flour, so the mixture cannot thicken properly and the gravy turns thin and watery. Squeezing and stirring it dry first keeps the texture smooth and concentrated.
Swap the spinach
How well each one fits the dish's main ingredients (butter, flour, veal, sugar, bread):
- Leekfits better
- Shallotfits better
- Arrowrootfits better
- Spinachthe original
Fit is the average pairing score against butter, flour, veal, sugar, bread. Candidates are from the same food group and used in at least 100 recipes.
