French or String Beans

Ingredients

Directions

Prepare the beans

  1. Remove the strings from the beans and cut them into pieces about ½ inch long.

Cook

  1. Boil the beans with ¼ teaspoon of baking soda for about 30 minutes until tender. Add salt while boiling.

  2. Alternatively, cook the beans in just enough water to tenderize them without baking soda.

Finish and serve

  1. Before serving, stir in 1 cup of sweet cream, 2 tablespoons of butter, and season with salt and pepper.

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

What each ingredient does

String beans
The main vegetable, cooked until tender and softened.
Baking soda
Raises the cooking water's alkalinity, helping the beans soften faster and stay green.
Sweet cream
Adds richness and body to the beans as they are finished.
Butter
Adds fat, flavor and a silky coating to the finished beans.

The step that matters

Cooking the beans until tender. Fresh beans need a long, gentle boil to soften fully. Stopping early leaves them fibrous, while overcooking makes them mushy and dull in color. Testing for tenderness matters more than the clock.

Swap the beans

How well each one fits the dish's main ingredients (cream, butter, pepper):

  1. Almondfits better
  2. Walnutfits about as well
  3. Pistachiofits about as well
  4. Beansthe original

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