Peas Soup Without Meat

Ingredients

Directions

Prepare the peas

  1. Rinse the peas and remove any worm-eaten ones.

  2. In a large pot, combine the peas and cold water, and boil until tender.

Make the soup

  1. In a skillet, melt the butter and fry the onions, carrots, and turnips until browned.

  2. Add the fried vegetables to the pot with the peas, along with black pepper and salt.

  3. Simmer gently, stirring often, until the vegetables are tender enough to pass through a sieve.

  4. Rub the mixture through a sieve into a clean pot and bring to a boil.

  5. Add the sliced celery and adjust seasoning if needed.

  6. Cook for an additional 20 minutes and serve hot with fried or toasted bread cubes.

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

What each ingredient does

Split peas
Form the body of the soup as they soften and break down into a thick purée.
Onions
Add savoury sweetness and depth when fried until browned.
Carrots
Contribute natural sweetness and colour, and help thicken the purée when sieved.
Turnips
Add mild sweetness and body to the soup once cooked and sieved.
Butter
Carries flavour into the frying step and adds richness to the finished soup.
Celery
Adds a fresh, aromatic note to the soup near the end of cooking.

The step that matters

Rubbing the mixture through a sieve. The vegetables must be fully tender before sieving, otherwise the purée stays grainy and clogs the sieve. Pressing it through removes fibres and skins, giving the smooth, thick texture the soup depends on.

Swap the peas

How well each one fits the dish's main ingredients (onion, carrot, turnip, butter, pepper, celery, vinegar):

  1. Beansfits better
  2. Lentilsfits better
  3. Chickpeafits better
  4. Peasthe original

Fit is the average pairing score against onion, carrot, turnip, butter, pepper, celery, vinegar. Candidates are from the same food group and used in at least 100 recipes.
