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 ↓
Green Peas and Asparagus Tips
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the vegetables
Boil the green peas and asparagus tips until tender.
Make the cream sauce
In a saucepan, melt the butter over medium heat.
Stir in the flour and cook for 1 minute.
Gradually add the cream, stirring constantly until thickened.
Add the minced parsley, red pepper, and salt to the sauce.
Serve
Serve the peas and asparagus topped with the cream sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melted with flour to form the base of the cream sauce, adding richness.
- Flour
- Cooked with melted butter to form a roux that thickens the cream sauce.
- Cream
- Thickens into the sauce and adds richness and body to the vegetables.
- Green peas
- Form the main vegetable base, providing sweetness and soft texture when boiled.
- Asparagus tips
- Provide the main vegetable flavor and tender texture when boiled.
The step that matters
Gradually add the cream while stirring constantly. Adding cream slowly while stirring keeps the flour-butter roux smooth, so lumps don't form and the sauce thickens evenly.
Swap the peas
