Why it works: Peas and pepper are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 5,331 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
A Peas Pudding
Ingredients
Directions
Prepare the peas
Remove any worm-eaten peas.
Wash the remaining peas well.
Soak the peas overnight in plenty of soft water.
Tie the peas in a thick pudding cloth, allowing room to swell.
Boil and mash
Cover with cold soft water and boil gently for 2 to 2½ hours.
Check if the peas are tender; if not, discard as bad quality.
Lift the peas into a colander.
Untie the cloth.
Crush the peas to a paste with a wooden spoon.
Stir in the butter, salt, and pepper.
Tie the mixture tightly in the cloth again.
Boil for an additional 30 minutes.
Serve
Turn the pudding onto a dish carefully to avoid breaking it.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Split peas
- Form the main body of the pudding, breaking down into a thick, smooth paste when boiled and crushed.
- Butter
- Adds fat and richness, giving the mashed peas a softer, smoother texture and flavour.
- Carbonate of soda
- Softens the peas in hard water so they break down more easily during boiling.
The step that matters
Boiling gently until tender. Peas cooked too hard or too fast can break apart unevenly or stay firm at the centre. A gentle boil lets the starch swell and soften the peas evenly, so they crush into a smooth paste.
Swap the peas
How well each one fits the dish's main ingredients (butter, pepper):
- Walnutfits better
- Black-eyed peafits better
- Almondfits better
- Peasthe original
Fit is the average pairing score against butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
