Why it works: Potato and tomato match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,798 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Dinner — Roast of Mutton with Potatoes
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Season the roast of mutton with salt and pepper.
Roast
Place the mutton in a roasting pan and surround it with potatoes.
Roast in the oven until the meat is cooked to your liking.
Serve
Serve with canned tomatoes and rhubarb sauce.
For dessert, serve baked custards and fruit cake.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Roast of mutton
- Provides the main meat, which becomes tender and browned as it roasts.
- Potatoes
- Roast alongside the meat, absorbing rendered fat and browning at the surface.
- Baked custards
- Set through gentle heat, giving a creamy, smooth dessert texture.
- Fruit cake
- Adds sweetness and a dense, moist crumb for dessert.
Swap the rhubarb
How well each one fits the dish's main ingredients (mutton, potato, tomato, sauce):
- Garlicfits better

- Capersfits better
- Rhubarbthe original
Fit is the average pairing score against mutton, potato, tomato, sauce. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
