Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Eggs Upon Toast
Ingredients
Directions
Make the eggs
Melt the butter in a frying pan over medium heat.
Stir in the beaten eggs, pepper, salt, and parsley.
Cook while stirring for about 3 minutes until just set.
Assemble and serve
Prepare slices of buttered toast, cutting them into rounds before toasting.
Spread the toast thickly with the ground or minced meat.
Top each slice with the egg mixture in mounds.
Serve in a hot dish garnished with parsley and pickled beets.

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 forms the topping when cooked gently.
- Butter
- Adds richness and fat to the pan, helping the eggs cook smoothly without sticking.
- Ground or minced tongue, chicken, or ham
- Provides savory meaty flavor and substance spread beneath the eggs on the toast.
The step that matters
Cook the eggs while stirring until just set. Eggs proteins coagulate with heat; cooking them gently while stirring keeps curds soft and moist. Overcooking squeezes out moisture, leaving them dry and rubbery.
Swap the parsley
How well each one fits the dish's main ingredients (butter, egg, pepper, chicken):
- Parsleythe original
- Tarragonfits about as well
- Thymefits less well
- Nutmegfits less well
Fit is the average pairing score against butter, egg, pepper, chicken. Candidates are from the same food group and used in at least 100 recipes.
