Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Mushrooms, on Toast
Ingredients
Directions
Prepare the mushrooms
Cut large mushrooms in half and skin them.
Blanch the mushrooms in hot water, then cool them in cold water and wipe dry.
Cook the mushrooms
Melt 2 oz of butter in a saucepan and add the mushrooms.
Sprinkle in a pinch of flour, then add salt, pepper, and parsley.
Add a little stock and cook the mushrooms for 15 minutes.
Add the juice of 1 lemon.
Fry the bread and serve
Fry the bread slices in 2 oz of melted butter on both sides.
Place the fried bread on a dish.
Remove the parsley from the mushrooms and pour the mushrooms with their sauce over the bread.
Serve very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Form the main body of the dish and release moisture that becomes the sauce.
- Butter
- Carries flavour and fat, and browns the bread when frying.
- Flour
- Thickens the cooking liquid into a light sauce around the mushrooms.
- Stock
- Adds savoury liquid that cooks the mushrooms and forms the sauce.
- Lemon juice
- Adds acidity that brightens the buttery mushrooms and sauce.
- Bread
- Provides a crisp, golden base that soaks up the mushroom sauce.
The step that matters
Blanch the mushrooms, then dry them well. Blanching briefly heats the mushrooms and cooling stops further softening. Wiping them dry matters because surface water would dilute the butter and flour, weakening the sauce and stopping the mushrooms from browning and absorbing flavour.
