Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Browns the onion and adds richness and a rounded flavour to the soup.
- Split peas
- Break down during the long simmer to thicken the soup and add body.
- Mixed vegetables
- Build the main flavour and, as they soften, add body and sweetness to the stock.
- Stock
- Forms the liquid base that carries the flavours and cooks the peas and vegetables.
- Oatmeal
- Added near the end to thicken the soup further, giving it a fuller texture.
The step that matters
Simmer gently for 2 hours. A gentle simmer lets the split peas and vegetables soften fully and release starch without the soup scorching on the base or turning cloudy from a hard boil.
