Bean Soup

Ingredients

Directions

Cook the beans

  1. Place the beans in a kettle and cover with water.

  2. Bring to a boil, then stir in the baking soda and let boil for a moment.

  3. Drain the water, add fresh water and the piece of pork, and cook until the beans are tender.

  4. Remove the beans and press them through a colander into the cooking water.

Season and finish

  1. Tie the thyme in a small bag and add it to the pot to simmer for a few minutes.

  2. Add the quartered hard-boiled eggs, sliced lemon, butter, salt, and pepper.

  3. For added flavor, include a piece of fresh raw beef until cooked through, or substitute with rich milk.

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

What each ingredient does

Beans
Form the body of the soup once cooked and pressed through a colander.
Baking soda
Raises the cooking water's alkalinity, helping the beans soften.
Pork
Adds savory meaty flavor to the cooking water.
Butter
Adds richness and a smooth, velvety mouthfeel to the soup.
Lemon
Adds acidity that brightens the flavor of the soup.

The step that matters

Pressing the beans through a colander. Pressing cooked beans breaks down their starchy cell walls so they blend into a smooth, thickened soup rather than staying grainy. Beans must be fully tender first, since firm beans resist pressing and give a coarse texture.

Swap the beans

How well each one fits the dish's main ingredients (pork, thyme, egg, lemon, butter, pepper, beef):

Fit is the average pairing score against pork, thyme, egg, lemon, butter, pepper, beef. Candidates are from the same food group and used in at least 100 recipes.
