Why it works: Peas and butter are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 4,887 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Split Pease Pudding
Ingredients
Directions
Cook the peas
Tie the split peas and baking soda in a cloth, leaving room to swell.
Boil in a pot of water for 2 hours.
Rub the cooked peas through a sieve.
Shape and serve
In a pan, combine the sieved peas with salt, pepper, and 1 ounce of butter.
Add a little of the boiling water and stir until thick.
Butter a basin and press the mixture into it to shape.
Turn out onto a serving dish or slice to serve with boiled pork.

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, setting into a firm, spoonable mass when cooked and sieved.
- Butter
- Adds richness and a smooth, glossy texture to the sieved peas.
- Baking soda
- Softens the peas' skins so they break down more easily during the long boil.
The step that matters
Stirring the sieved peas until thick. Adding too much boiling water or stopping too early leaves the mixture loose and unable to hold its shape when pressed into the basin. Cooking it down until thick lets the starch in the peas set as it cools.
Swap the white pepper
How well each one fits the dish's main ingredients (peas, butter):
- Mintfits better
- Tarragonfits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against peas, butter. Candidates are from the same food group and used in at least 100 recipes.
