Why it works: Pasta and capers share more aroma than cooks usually use. They rank in the top 2% of all ingredient pairs, and 89 recipes mention both. Both carry coumarin, which smells sweet, hay. The science ↓
The recipe
Ingredients
Contains: milk, wheat, tree nuts (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the hazelnuts
Preheat oven to 325°F.
Spread hazelnuts in a small baking pan.
Bake until toasted and fragrant, stirring once, about 15 minutes. Cool slightly.
Rub briskly in a kitchen towel to remove skins. Set aside.
Cook the pasta and beans
Bring a large pot of lightly salted water to a boil. Add pasta. Stir to prevent sticking.
Cook pasta until just tender, about 8 minutes. Drain. Rinse under cold water. Drain well. Set aside.
Bring a large saucepan of water to a boil. Add green beans.
Cook until just crisp-tender, about 3 minutes. Drain. Rinse under cold water. Drain well. Set aside.
Assemble and serve
In a large shallow serving bowl, whisk together all vinaigrette ingredients.
Add pasta, green beans, toasted hazelnuts and pimientos and toss to combine.
Sprinkle with parsley and capers if desired. Scatter cheese around edge of salad.
Serve at room temperature or slightly chilled.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hazelnuts
- Toasting brings out a nutty aroma and adds a crisp, crunchy texture to the salad.
- Penne or ziti pasta
- Forms the bulk of the salad and holds the vinaigrette and other ingredients.
- Green beans
- Add a crisp-tender texture and fresh, grassy flavor.
- Goat cheese
- Adds tangy, creamy richness that contrasts with the vinaigrette and vegetables.
- Roasted red peppers
- Add sweetness and soft texture, along with color.
The step that matters
Bake the hazelnuts until toasted and fragrant. Toasting develops the nut's flavor through browning reactions, but over-baked hazelnuts turn bitter, so watch them closely while stirring once.
Flavor stand-ins for the capers
The recipe marks capers as optional. How well each one fits the dish's main ingredients (hazelnut, pasta, green beans, pepper, parsley, goat cheese):

Fit is the average pairing score against hazelnut, pasta, green beans, pepper, parsley, goat cheese. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
