Why it works: Pine and hazelnut share more aroma than cooks usually use. They rank in the top 5% of all ingredient pairs, and 13 recipes mention both. Both carry coumarin, which smells sweet, hay. The science ↓
The recipe
Serves 4Ingredients
Contains: egg, milk, wheat, tree nuts (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Mix the flour with a pinch of sea salt and make a well in the middle. Add the 2 eggs and a splash of water, then work into a smooth dough, about 8 minutes. Wrap and rest at room temperature for 30 minutes.
Heat the oven to 180°C (350°F). Spread the pine nuts and hazelnuts on a tray and roast 6 to 8 minutes until golden. Cool, then roughly chop the hazelnuts.
Finely chop the shallot, garlic and 3 large sage leaves. Warm some olive oil in a pan, soften the shallot for 2 minutes, add the garlic and cep mushrooms, and cook 8 to 10 minutes until dry and golden. Season, stir in the sage, squeeze in the lemon quarter, and cool.
Beat the remaining egg in a small bowl. Roll the pasta dough very thin and cut into 5 cm (2 in) rounds.
Place a small spoonful of filling in the centre of each round. Brush the edge with beaten egg, fold into a half-moon, press out the air and seal, then wrap the two corners around a finger to form tortellini. Keep covered until cooking.
Melt the butter in a wide pan over medium heat until it foams and turns nutty brown. Add the 8 sage leaves and fry about 1 minute until crisp. Remove from heat and add a squeeze of the half lemon.
Bring a large pan of salted water to a boil. Cook the tortellini 3 to 4 minutes until tender and floating, then drain.
Toss the tortellini gently in the sage butter. Serve topped with the roasted nuts and freshly ground black pepper.

Fit is the average pairing score against pasta, egg, olive, mushroom, pepper, shallot, garlic. 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).
