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 ↓
Old-fashioned Creamed Onions and Mushrooms
Ingredients
Directions
Cook the onions
In a large pan, over high heat, bring onions and enough water to cover to boil.
Reduce heat to low; simmer covered 30 minutes or until onions are tender.
Drain onions.
Slip off skins.
Make the mushrooms and sauce
Meanwhile, in a large skillet over medium heat, melt margarine; add mushrooms.
Cook about 5 minutes. Stir occasionally until tender and lightly browned.
With a slotted spoon, remove mushrooms to a bowl.
Stir flour into the drippings remaining in the skillet until well mixed.
Over medium-low heat, gradually stir in milk. Cook, stirring frequently until thickened and smooth.
Remove from heat. Stir in sherry, salt, paprika and pepper.
Combine and finish
Add the onions to the skillet along with the mushrooms.
Over low heat, cook about 5 minutes. Stir constantly until the vegetables are heated through and coated with sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the milk and drippings into a smooth, creamy sauce.
- Margarine
- Provides fat for cooking the mushrooms and forming the sauce base.
- Milk
- Forms the liquid base of the cream sauce.
- Mushrooms
- Soften and brown in the fat, adding savory flavor and body.
- Onions
- Become tender after simmering and form the main vegetable in the dish.
The step that matters
Stirring the milk into the roux. Adding milk gradually over medium-low heat while stirring keeps the flour mixture smooth; adding it all at once or cooking too hot can cause lumps or scorching on the bottom of the skillet.
