Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Bind the cheese and parsley mixture and thicken it as it heats.
- Hard-boiled eggs
- Provide the bulk and soft, tender texture of the dish.
- Milk
- Adds moisture and makes the egg mixture creamy rather than dry.
- Grated cheese
- Adds savoury flavour and richness, and helps the mixture cling together.
- Onion
- Browning the onion first builds sweet, savoury flavour in the pan.
The step that matters
Stirring the egg yolk mixture over low heat. Egg yolks thicken and can scramble or curdle if the heat is too high. Gentle, low heat over 7-8 minutes lets the mixture set smoothly and stay creamy.
