Why it works: Potato and carrot match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,107 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
Potato Mould
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the mixture
Mash the boiled potatoes and carrots together.
Pass the mixture through a fine wire sieve.
Mix in warm milk and butter until well combined.
Bake and serve
Place the mixture in a buttered mold.
Bake in a 400°F (200°C) oven for 10 minutes.
Turn out onto a hot dish and brown in the oven.
Serve with curry, tomato, or chutney sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Boiled potatoes
- Form the bulk of the mould, giving a soft, starchy structure once mashed.
- Boiled carrots
- Add body and colour to the mashed mixture along with the potatoes.
- Warm milk
- Moistens the mash so it becomes smooth and easy to shape in the mould.
- Butter
- Adds richness and fat, improving flavour and softness of the mash.
The step that matters
Pass the mixture through a fine wire sieve. Sieving breaks up lumps and fibres so the mash turns smooth and holds together evenly when turned out. Skipping it leaves a grainy, crumbly texture.
Swap the carrot
How well each one fits the dish's main ingredients (potato, milk, butter):
- Chivefits better
- Asparagusfits better
- Onionfits better
- Carrotthe original
Fit is the average pairing score against potato, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
