Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the mixture as they set gently and add richness to the sauce.
- Cheese
- Melts into the sauce, giving it body, saltiness, and a rich, creamy texture.
- Tomatoes
- Provide the liquid base and a bright acidity that balances the rich cheese and yolks.
- Butter
- Adds fat for a smooth mouthfeel and carries the onion's flavor into the dish.
- Onion
- Adds savory aroma and depth as it softens in the melted butter.
The step that matters
Mix in the beaten egg yolks. Egg yolks scramble if they meet very hot liquid too quickly. Stir them in steadily and keep the mixture hot but not boiling so they thicken smoothly.
Swap the onion
