Green Pea Soup of India
Ingredients
Directions
Make the soup
Melt the butter in a saucepan over low heat.
Add the peas, parsley, and green onions, and cook until thoroughly stewed.
Pound the mixture in a mortar or rub through a colander.
Return the mixture to the saucepan and add enough stock to achieve desired consistency.
Keep on low heat to simmer, avoiding boiling to preserve the green color.
Serve
Just before serving, add fried bread snippets.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Form the main body of the soup and give it its flavour and thickness when pureed.
- Butter
- Adds richness and carries flavour when the vegetables are first cooked gently.
- Green onions
- Add a mild onion aroma that builds the soup's savoury base.
- Parsley
- Adds fresh, herbal aroma and a bright green note.
The step that matters
Keep the soup at a gentle simmer. Boiling can dull the bright green colour of the peas and their chlorophyll breaks down with prolonged high heat, so the soup should be kept just under a boil.
Swap the peas
How well each one fits the dish's main ingredients (butter, parsley, onion, bread):
- Chickpeafits better
- Beansfits better
- Lentilsfits about as well
- Peasthe original
Fit is the average pairing score against butter, parsley, onion, bread. Candidates are from the same food group and used in at least 100 recipes.
