Why it works: Parsnip and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 1,096 recipes mention both. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
The recipe
6 servingsIngredients
Contains: milk, wheat (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.
Preheat the oven to 425°F (220°C).
Melt the butter in a large pot over medium heat. Add the leeks and mushrooms and cook about 5 minutes, stirring, until softened.
Add the parsnips, carrots and sweet potato and cook 3 minutes, stirring. Sprinkle in the flour and dried thyme and stir for 1 minute.
Slowly stir in the vegetable broth. Bring to a simmer and cook about 10 minutes, until the vegetables are tender and the sauce thickens. Season with salt, black pepper and hot pepper sauce, then transfer to a 2-quart baking dish.
Stir the biscuit baking mix and milk together until a soft dough forms. Drop spoonfuls over the hot filling and spread lightly.
Bake 15 to 20 minutes, until the topping is golden brown and the filling is bubbling. Let stand 5 minutes before serving.

Fit is the average pairing score against parsnip, carrot, butter, mushroom, leek, flour, thyme. 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).
