Why it works: Pepper and parsnip are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 1,109 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Split-peas Pudding
Ingredients
Directions
Prepare the peas
Soak the split peas in water overnight.
Drain the peas and place them in a loose cloth to allow swelling.
Cook and shape
Boil the peas for 4 hours or until tender.
Rub the cooked peas through a colander until smooth.
Mix in the butter and salt thoroughly.
For a richer pudding, add the beaten eggs with the butter.
Tie the mixture tightly in the cloth and boil for 30 minutes.
Serve
Serve with melted butter poured over the pudding and garnish with parsnips.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yellow split peas
- Form the bulk of the pudding and set into a firm, spoonable texture when cooked and pressed.
- Butter
- Adds richness and a smooth mouthfeel to the mashed peas.
- Eggs
- Optional; bind the mixture and help it set more firmly when boiled.
The step that matters
Tie the mixture tightly in the cloth. If the cloth is loose, the pudding can break apart or absorb too much water during boiling. A snug wrap keeps it compact and holds its shape.
Swap the parsnip
How well each one fits the dish's main ingredients (peas, butter, pepper, egg):
- Asparagusfits better
- Capsicumfits better
- Spinachfits better
- Parsnipthe original
Fit is the average pairing score against peas, butter, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
