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 ↓
Asparagus Tops, with Truffles, Imperial
Ingredients
Directions
Prepare the asparagus
Prepare the asparagus tops by cutting them into 1-inch pieces.
Cook the asparagus until tender, then place them in a flat saucepan with butter.
Season with coarse sea salt and black pepper, and warm thoroughly.
Assemble and serve
Transfer the asparagus to a serving dish, leaving space in the center.
Fill the center with the julienne truffles.
Reduce the Madeira wine and pour it over the truffles.
Sprinkle chopped parsley over the dish before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus tops
- Form the main bulk of the dish and provide its tender, vegetal texture.
- Butter
- Adds richness and a silky mouthfeel as it coats the warm asparagus.
- Truffles
- Contribute a concentrated earthy aroma that defines the dish's flavor.
- Madeira wine
- Reduced to a concentrated sauce that adds sweetness and depth to the truffles.
The step that matters
Reducing the Madeira wine. Reducing concentrates the wine's sugars and flavors as water evaporates. Cooking it too briefly leaves a thin, harsh sauce, while cooking it too long can make it syrupy and overly sweet.
Swap the asparagus
How well each one fits the dish's main ingredients (butter, pepper, truffle, madeira wine, parsley):
- Shallotfits better
