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.
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 squeeze of lemon juice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus tops
- Form the body of the sauce and give its fresh, vegetable flavour.
- Egg yolks
- Thicken and enrich the sauce as they set gently with the warm asparagus.
- Thickened veal gravy
- Adds savoury depth and body to the asparagus in the first serving option.
- Melted butter
- Adds fat and a smooth, rich texture to the asparagus in the alternative serving option.
The step that matters
Boil the asparagus until tender. Boiling in plenty of salted water cooks the asparagus evenly and keeps it bright green. Undercooked pieces stay fibrous and make the sauce grainy, while overcooking dulls the colour and flavour.
Swap the asparagus
