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, giving it its vegetable flavour and texture.
- Egg yolk
- Thickens the mixture gently as it heats and adds richness.
- Butter
- Adds fat and richness, carrying flavour over the finished dish.
- Bread
- Provides a crisp toasted base that holds the mixture.
The step that matters
Heating the mixture gently with the egg yolk. Egg yolk thickens when heated, but too much heat can curdle it into lumps. Heating gently keeps the mixture smooth and creamy.
Swap the onion
How well each one fits the dish's main ingredients (asparagus, pepper, egg, butter, bread):
