Ingredients
Directions
Prepare the spinach
Cook the spinach in stock, drain, and chop finely.
Season with pepper and salt, then form into a ring on a hot dish.

Pour the egg mixture into the ring of spinach and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a soft, tender mass that holds the dish together.
- Spinach
- Forms the ring base, adding bulk, earthy flavor and a tender texture.
- Tomato pulp
- Adds moisture and bright acidity to the egg mixture.
- Melted butter
- Coats the pan and adds richness, helping the eggs cook gently without sticking.
The step that matters
Stir the eggs until lightly set. Egg proteins set with heat, so stirring over gentle heat keeps curds small and tender. Overcooking squeezes out moisture and makes the eggs dry and rubbery.
Swap the tomato
How well each one fits the dish's main ingredients (spinach, pepper, egg, butter):
- Asparagusfits better
- Chivefits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against spinach, pepper, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
