Why it works: Onion and chicory share more aroma than cooks usually use. They rank in the top 11% of all ingredient pairs, and 67 recipes mention both. Both carry coumarin, which smells sweet, hay. The science ↓

Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Heat the oven to 400°F (200°C). Beat the butter with the crumbled Roquefort and a little black pepper until smooth, then chill it while you cook.
Toss the potato slices with 4 tbsp of the olive oil, the thyme leaves, salt and pepper. Spread them over the bottom of a large roasting dish and roast for 20 minutes.
Cut the red onions into thick wedges and halve, core and quarter the pears. Toss them with the remaining 2 tbsp olive oil, the brown sugar and the crème de cassis if using.
Season the spare rib chops with salt and pepper. Brown them in a hot skillet over medium-high heat for 2 minutes per side, then move them to a plate.
Scatter the onions and pears around the potatoes and set the chops on top. Roast for 20 to 25 minutes until the thickest part of the pork reaches 145°F (63°C), then rest for 3 minutes.
Toast the walnuts in a dry pan over medium heat for 3 to 4 minutes, shaking often, then roughly chop them.
Whisk the red wine vinegar with the walnut oil and a pinch of salt and pepper. Toss the watercress and chicory with this dressing and the walnuts.
Top each hot chop with a slice of the chilled Roquefort butter so it melts. Serve with the potatoes, onions, pears and salad.

Fit is the average pairing score against butter, potato, olive, pepper, onion, pear, sugar. 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).
