Why it works: Apple and cider match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 1,042 recipes mention both. Both carry ethyl 2-methylbutyrate, which smells fruity, apple. The science ↓
The recipe
Serves 4Ingredients
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Preheat the oven to 425°F (220°C). Spread the chopped onion, parsnips and sweet potato in a single layer on a rimmed baking sheet.
Drizzle the vegetables with olive oil, sprinkle with the chopped fresh thyme or rosemary, and toss until evenly coated.
Roast for 15 minutes, until the vegetables begin to soften and brown at the edges.
While the vegetables roast, simmer the apple cider in a small saucepan over medium heat for about 8 minutes, until it reduces by about half and turns syrupy.
Pour the reduced cider over the hot vegetables and toss to coat. Roast 10 more minutes, until the vegetables are tender when pierced with a fork and glazed.

Fit is the average pairing score against apple, cider, parsnip, sweet potato, thyme, olive. 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).
