Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus
- Forms the main body of the dish and gives it its vegetable flavour.
- Butter
- Adds richness and fat, carrying flavour through the sauce.
- Flour
- Thickens the stock into a smooth sauce as it cooks.
- Stock
- Provides the liquid that the vegetables stew in and the sauce is built on.
- Lettuce
- Softens as it stews, adding moisture and a mild, tender texture.
- Onion
- Adds savoury aroma and depth to the stewed sauce.
The step that matters
Stew gently until the sauce thickens. Flour thickens liquid only as its starch swells in simmering heat. Stewing too hard can break the sauce or scorch the bottom, so keep the heat low and stir.
Swap the onion
How well each one fits the dish's main ingredients (asparagus, lettuce, endive, butter, flour, pepper):
- Beetrootfits better
