Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Form the main body of the dish, providing protein structure and substance.
- Butter
- Adds richness and carries flavor while the onions and tomatoes fry and brown.
- Onions
- Contribute sweetness and aroma as they soften and caramelize in the fat.
- Tomatoes
- Add acidity and moisture that break down into the sauce.
- Bread crumbs
- Absorb liquid and thicken the mixture, giving it body.
- Stock
- Supplies the main liquid that forms the sauce and carries savory flavor.
The step that matters
Place the egg slices in the liquid and warm them through.. Egg whites and yolks turn rubbery and dry when heated too hard or too long. Keeping the liquid gentle lets the slices warm through while staying tender.
