Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Jerusalem artichokes
Form the body of the puree, providing the main flavour and thickening solids once pressed.
Flour
Thickens the milk mixture so the puree holds body when cooked.
Milk
Makes up the liquid base, giving the puree a smooth, creamy texture.
Egg yolks
Enrich and thicken the puree as they set gently, adding richness and smoothness.
Butter
Adds fat for flavour and a rich, silky mouthfeel.

The step that matters

Do not boil again after adding the egg yolks. Egg yolks thicken by gentle heat and will curdle or turn grainy if the puree boils once they are stirred in, spoiling the smooth texture.
