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 puree and supplies its green flavor and texture.
Butter
Adds richness and a smooth, silky mouthfeel to the finished puree.
Thickened chicken broth or cream
Provides the liquid base and body that carries the puree's texture.
Egg yolks
Thicken the puree as they heat, giving it a smooth, velvety body.

The step that matters

Adding the egg yolks. Egg yolks thicken by gentle heat. If the puree boils after the yolks go in, they can scramble and curdle, leaving the texture grainy. Add them off the heat or at low heat, stirring constantly.

Swap the asparagus
