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 ↓
Mushrooms
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the filling
In a stewpan, combine water or vegetable broth, pepper, salt, parsley, green onions, and chopped mushrooms.
Boil over low heat until thick.
Assemble and bake
Beat the eggs and mix them with the mushroom mixture.
Butter small cups and fill them with the mixture.
Bake in a 400°F (200°C) oven until set.
Serve
Turn out onto a dish and serve with stewed mushrooms.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set when baked, giving the bake its firm, sliceable structure.
- Mushrooms
- Add earthy flavor and moisture that cooks down into the filling.
- Vegetable broth
- Provides liquid and savory flavor, reduced to thicken the mushroom mixture.
- Green onions
- Add mild onion aroma and a fresh bite to the filling.
The step that matters
Bake until set. Eggs firm as their proteins coagulate with heat. Pulling the cups too early leaves a runny centre, while overbaking makes the texture rubbery.
Swap the onion
How well each one fits the dish's main ingredients (pepper, parsley, mushroom, egg, butter):
- Shallotfits better
- Capsicumfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against pepper, parsley, mushroom, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
