Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Split peas
- Break down during long simmering to thicken the soup and give it body.
- Bacon
- Its fat carries flavour into the onions and carrots and adds savoury depth.
- Onions
- Softened in bacon fat, they add sweetness and aromatic base flavour.
- Carrots
- Softened in bacon fat, they add natural sweetness and body to the soup.
The step that matters
Simmer for 2 hours. Split peas must cook long enough to soften fully and break down; undercooked peas leave the soup grainy and thin. Keep the heat low so the soup does not scorch on the bottom of the pan.
Swap the onion
How well each one fits the dish's main ingredients (peas, carrot, mint, pepper):
- Capsicumfits better
- Cucumberfits better
- Lettucefits better
- Onionthe original
Fit is the average pairing score against peas, carrot, mint, pepper. Candidates are from the same food group and used in at least 100 recipes.
