Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Form the body of the dish and absorb butter and sugar as they cook.
- Butter
- Adds richness and fat, carrying flavour into the carrots.
- Milk
- Forms the liquid base of the sauce, adding creaminess as it reduces.
- Egg yolks
- Thicken the milk into a smooth, lightly set sauce.
- Sugar
- Adds sweetness to the carrots as they cook in the water.
The step that matters
Stirring the egg yolks into the milk. Hot milk can scramble egg yolks into lumps if they are added carelessly. Keep the heat gentle and stir steadily so the yolk proteins set slowly and evenly, thickening the sauce smoothly.
Swap the carrot
