Why it works: Asparagus and lemon work together. They rank in the top 6% of all ingredient pairs, and cooks put them together in 704 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Steamed Asparagus
Ingredients
Directions
Prepare the asparagus
Trim the asparagus.
Steam the asparagus in a jam‑pot nearly filled with boiling water, placed in a large saucepan half full of boiling water, and tightly covered for nearly an hour.
Make the sauce
In an enamelled saucepan, melt the butter over low heat.
Add the cream, egg yolk, and lemon juice to the melted butter.
Stir the mixture over low heat for three minutes.
Serve
Serve the asparagus with the sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts to form the rich base of the sauce, adding fat and a smooth mouthfeel.
- Egg yolk
- Thickens the warm sauce as it sets gently, giving it a creamy, emulsified texture.
- Cream
- Adds fat and moisture, making the sauce smoother and milder.
- Lemon juice
- Adds acidity that brightens the sauce and balances its richness.
The step that matters
Stir the sauce over low heat. Egg yolk thickens through gentle heat; if the mixture gets too hot, the proteins can scramble and the sauce turns grainy instead of smooth.
Swap the lemon
How well each one fits the dish's main ingredients (asparagus, butter, cream, egg):
- Lemonthe original
- Coconutfits about as well
- Vanillafits about as well
- Avocadofits less well
Fit is the average pairing score against asparagus, butter, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
