Why it works: Potato and parsnip work together. They rank in the top 6% of all ingredient pairs, and cooks put them together in 353 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
Roast Beef with Yorkshire Pudding
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C) for one hour.
Cook the tapioca in a cup of water until soft.
Heat fat in a pan for the beef.
Roast
Place the cranberries and Yorkshire pudding in the oven on the bottom shelf.
Add the potatoes on the bottom shelf with a tin underneath to prevent burning.
At 11:30, place the beef on the bottom shelf and Yorkshire pudding in patty pans above.
Turn the potatoes and place parsnips with a little water on the lower shelf.
Heat stock on the upper shelf.
After 45 minutes, turn the meat, remove cranberries, and place parsnips on the upper shelf.
Finish cooking until everything is ready by 1 o'clock.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Roast beef
- Provides the main protein; slow roasting in fat browns the outside and keeps the inside tender.
- Flour
- Forms the batter structure that sets into the rising Yorkshire pudding.
- Eggs
- Bind the batter and help it puff and set as it bakes.
- Milk
- Adds moisture to the batter and helps it brown and rise.
- Potatoes
- Starch that softens and browns in the oven, giving a sturdy side dish.
The step that matters
Heat the fat before the batter goes in. Batter poured into very hot fat sets quickly on contact, which helps it rise high and crisp. Cold fat lets the batter spread and stay flat and dense.
Swap the parsnip
How well each one fits the dish's main ingredients (beef, potato, flour, milk, egg, pepper):
- Chivefits better
- Asparagusfits better
- Capsicumfits better
- Parsnipthe original
Fit is the average pairing score against beef, potato, flour, milk, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
