Why it works: Potato and celery are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,047 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Cream Pea Soup
Ingredients
Directions
Prepare the peas
Soak the dried peas overnight in water.
In the morning, cook the peas in boiling water for 4-5 hours until very tender.
Rub the cooked peas through a colander to remove the skins.
Make the soup
Cook the sliced potatoes in a small amount of water until tender, then rub through a colander.
Combine the sifted peas, prepared potatoes, and enough milk to make 3½ pints total.
Return to the fire and add the celery; simmer for 10-15 minutes.
Remove the celery, add salt to taste, and stir in the thin cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried peas
- Form the body of the soup, thickening it as they break down into a purée.
- Potatoes
- Add starch that gives the soup a smoother, thicker body.
- Milk
- Provides the liquid base and a soft, creamy mouthfeel.
- Thin cream
- Adds fat for richness and a silkier texture.
- Celery
- Contributes a mild, savoury aroma as it simmers in the soup.
The step that matters
Cooking the peas until very tender. Dried peas must cook long enough for their starches to fully soften; undercooked peas leave the purée grainy and stop it from passing smoothly through the colander.
