Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and thicken as they are stirred, binding the asparagus into a creamy mixture.
- Butter
- Adds richness and a smooth, silky texture to the eggs.
- Young asparagus
- Provides the green vegetable body and a tender, slightly grassy bite.
The step that matters
Stir the mixture until thick. Eggs set with heat, and overcooking them makes them curdle and dry, so stir steadily and remove them while still soft and creamy.
Swap the asparagus
