Why it works: Parsley and pepper 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 ↓
Fried Eggs with Ragout of Mushrooms
Ingredients
Directions
Prepare
Clean the mushrooms and slice them if large.
Finely chop the onions and parsley.
Make the ragout
Melt part of the butter in a pan, then add the parsley, onions, vinegar, nutmeg, pepper, salt, and sugar.
Break 2 eggs into a bowl, moisten the yolks with 1 tablespoon of cold water, and stir in the remaining butter.
Combine the egg mixture with the onion and parsley mixture.
Gradually add the mushrooms and simmer gently for 10 minutes; keep warm.
Fry and serve
Fry the remaining eggs in hot butter or fat.
Serve the fried eggs over the mushroom ragout.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the bulk and savory, earthy body of the ragout.
- Eggs
- Bind the ragout, adding richness and thickening, and serve as the fried topping.
- Butter
- Adds fat for richness and carries flavor while frying and cooking the onions and parsley.
- Vinegar
- Adds acidity that brightens the flavor and balances the richness of the eggs and butter.
- Green onions
- Contribute aroma and a mild sweetness as they soften in the butter.
- Parsley
- Adds a fresh, herbal aroma that lifts the earthy mushrooms.
The step that matters
Simmer the ragout gently. Egg proteins set at around 70°C and can curdle or turn grainy if the mixture boils or heats too fast. A gentle simmer keeps the egg-enriched ragout smooth and creamy.
Swap the onion
How well each one fits the dish's main ingredients (egg, mushroom, butter, vinegar, parsley, nutmeg, pepper):
