Haricot Soup

Ingredients

Directions

Prepare the beans

  1. Pour boiling water over the Haricot beans and let them stand covered for 5 minutes.

  2. Remove the skins from the beans as you would blanch almonds.

Cook the soup

  1. Boil the skinned beans in 1 quart of water with the pickled pork or bacon and onions.

  2. Cook until the beans are tender, about 3 hours, adding water as needed to prevent sticking.

Finish and serve

  1. Rub the mixture through a sieve and add enough broth or water to achieve desired thickness.

  2. Season to taste and add finely minced meat from the soup before serving.

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

What each ingredient does

Haricot beans
Form the body of the soup and thicken it when pureed through a sieve.
Pickled pork or bacon
Adds savory fat and salty flavour to the cooking water.
Onions
Add aromatic sweetness and depth as they soften in the broth.

The step that matters

Cook until the beans are tender. Dried beans must be fully softened before sieving; undercooked beans stay firm and grainy, and adding water as needed prevents scorching on the base of the pot.

Swap the beans
