Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Asparagus Sauce
Ingredients
Directions
Prepare the asparagus
Wash and drain the asparagus tops, cutting them into half-inch lengths.
Boil the asparagus in plenty of salted water for about 15 minutes or until tender.
Drain the asparagus in a strainer.
Finish and serve
To serve, mix the asparagus with thickened veal gravy and the yolks of two eggs, seasoning with salt and cayenne.
Alternatively, mix the asparagus with melted butter and a little lemon juice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus tops
- Provide the main flavour and bulk of the sauce once cooked until tender and pureed or mixed.
- Thickened veal gravy
- Adds body and savoury depth to the sauce.
- Egg yolks
- Add richness and help thicken the sauce as they set gently with heat.
- Melted butter
- Adds fat and smoothness, giving the asparagus a rich, silky coating.
- Lemon juice
- Adds acidity that brightens the flavour of the asparagus and butter.
The step that matters
Adding the egg yolks. Egg yolks thicken through gentle heat and can scramble if they are added to very hot liquid too quickly. Stir them in gradually and keep the sauce warm rather than boiling so it stays smooth.
Swap the asparagus
