Why it works: Pepper and onion are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Steak or Kidney Pudding
Ingredients
Directions
Prepare
If using kidney, split and soak it, then season with salt and pepper.
Make a paste by mixing suet, flour, and milk; roll it out.
Line a basin with some of the paste.
Assemble and cook
Place the kidney or steak in the basin and cover with more paste, pinching the edges to seal.
Cover with a cloth and boil for a considerable time.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Suet
- Adds fat that keeps the paste rich and tender as it cooks.
- All-purpose flour
- Forms the paste that wraps and holds the filling together.
- Kidney
- Provides the main meaty filling that cooks inside the paste.
- Milk
- Adds moisture so the flour forms a workable, pliable dough.
The step that matters
Sealing the paste. Pinching the edges closed traps steam and juices inside during the long boil. A gap lets water seep in, leaving the filling soggy and the paste waterlogged.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (pepper, flour, milk):
- Capsicumfits better
- Arrowrootfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against pepper, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
