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 and wash the remainder well.
Soak the peas in plenty of soft water overnight.
Tie the peas in a thick pudding cloth, leaving room for them to swell.
Boil and mash
Cover with cold soft water and boil gently for 2 to 2.5 hours. If not tender, they are of bad quality.
Lift the peas into a colander, untie the cloth, and crush them to a paste with a wooden spoon.
Stir in the butter, salt, and pepper.
Tie the mixture tightly in the cloth again and boil for an additional 30 minutes.
Serve
Turn the pudding gently into a dish and 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 bulk of the pudding and, once cooked and crushed, set into a thick, scoopable paste.
- Butter
- Adds richness and fat, giving the mashed peas a smoother, silkier mouthfeel.
The step that matters
Boiling until fully tender. Split peas must cook long enough for their starches to soften fully; undercooked peas stay grainy and will not 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.
