Why it works: Bread and butter 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 ↓
Asparagus on Toast
Ingredients
Directions
Cook the asparagus
Cook the asparagus slowly for half an hour.
Ten minutes before done, add a little coarse sea salt.
Assemble the toast
Toast the bread and butter it well.
Pour 1-2 tablespoons of liquor over the toast.
Carefully place the asparagus on the toast.
Mix a piece of butter with a little flour, then add pepper and coarse sea salt.
Stir this mixture into the liquor and pour it over the asparagus.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus
- Forms the main vegetable layer and provides the tender texture of the topping.
- Butter
- Adds richness and helps the toast brown and taste savoury.
- Flour
- Thickens the butter and liquor mixture into a light sauce.
- Liquor (such as white wine)
- Adds acidity and moisture to the sauce poured over the asparagus.
The step that matters
Stir the butter and flour mixture into the liquor. Stirring the butter and flour into the liquor helps the flour disperse evenly, so the sauce thickens smoothly instead of forming lumps.
Swap the asparagus
How well each one fits the dish's main ingredients (bread, butter, white wine, flour, pepper):
- Shallotfits better
- Capsicumfits about as well
- Leekfits about as well
- Asparagusthe original
Fit is the average pairing score against bread, butter, white wine, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
