Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Form the main body of the dish, giving sweet, tender bulk to the stew.
- Butter
- Adds richness and carries flavour, helping the vegetables soften gently in the pan.
- Eggs
- Yolks thicken the milk or cream into a silky, lightly set sauce when kept below boiling.
- Lettuce
- Wilts into the peas, adding moisture and a soft, mild body to the stew.
- Green onions
- Add a mild, sharp aroma that softens and sweetens during slow simmering.
- Milk or cream
- Adds moisture and richness, forming the base of the thickened sauce with the yolks.
The step that matters
Stir in the beaten yolks of the eggs. Egg yolks thicken when heated gently but curdle and turn grainy if the mixture boils. Remove from heat or keep it below boiling once the yolks go in, stirring constantly.
Swap the onion
