Rtch Peas Soup

Ingredients

Directions

Prepare the base

  1. Drain the soaked peas and place them in a large soup pot with the brown gravy stock.

  2. Boil gently for 30 minutes.

  3. In a separate pan, fry the onions, carrots, and turnips in butter until browned.

  4. Add the fried vegetables to the soup and simmer until the peas are reduced to pulp.

  5. Season with salt and cayenne pepper.

  6. Boil for 2-3 minutes.

Strain and thicken

  1. Pass the soup through a sieve, pressing the vegetables to extract flavor.

  2. Return the strained soup to a clean saucepan, adding fresh stock if too thick.

  3. If too thin, reduce by boiling quickly.

  4. Add the sliced celery and cook until tender.

  5. Mix curry powder with a few spoonfuls of soup.

  6. Add the mixture back when the soup begins to boil.

Serve

  1. Serve the soup hot with small fried or toasted sippets.

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

What each ingredient does

Yellow split peas
Break down into pulp, giving the soup its body and thickness.
Brown gravy stock
Supplies the liquid base and savoury flavour for the whole soup.
Onions
Browning in butter builds savoury, sweet depth in the soup.
Carrots
Add sweetness and body as they soften and break down.
Turnips
Add earthy flavour and body as they soften and break down.
Celery
Adds a fresh, aromatic vegetable note and a little body.

The step that matters

Simmering the peas until they become pulp. Split peas must cook long enough to soften fully and break down; undercooked peas leave the soup grainy and thin. Stopping too early is the usual error.

Swap the peas
