Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Asparagus
Ingredients
Directions
Boil the asparagus
Boil the asparagus in water for 30 minutes.
Carefully remove the asparagus, preventing the heads from falling off.
Serve on toast
Lay the asparagus on toast and untie the bundles, allowing them to fall in one direction.
Pour melted butter mixed with lemon juice over the asparagus or serve separately.
Make the cream sauce
In a flat saucepan, place tender asparagus pieces and cover with milk or cream.
Heat until boiling, then add butter mixed with flour, and season with salt and pepper.

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 and becomes tender when boiled.
- Milk or cream
- Adds moisture and a creamy body to the sauce.
- Butter
- Adds fat, richness and flavour to the sauce and topping.
- Flour
- Thickens the liquid into a sauce as its starch swells when heated.
The step that matters
Adding the butter and flour to the boiling milk or cream. Flour thickens liquid only when its starch is heated in the liquid, and it clumps if dropped in dry. Mixing it with butter first spreads the starch evenly, so the sauce thickens smoothly instead of lumping.
Swap the asparagus
How well each one fits the dish's main ingredients (milk, butter, flour, pepper):
- Potatofits better
- Capsicumfits better
- Chivefits about as well
- Asparagusthe original
Fit is the average pairing score against milk, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
