Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Onions
Softens into the broth and adds savoury sweetness as it cooks.
Potatoes
Break down slightly as they cook, thickening the broth and adding body.
Tomatoes
Add acidity and colour, giving the soup its base flavour.
Peas
Add sweetness and texture to the finished soup.

The step that matters

Boiling for 1 hour. A long, steady boil lets the onions and potatoes soften fully and the flavours meld. Boiling too hard can break up the potatoes and cloud the broth.
