Beans, Boiled French

Ingredients

Directions

Prepare

  1. Cut off the heads and tails of the beans and remove the strings by slicing a thin strip on each side.

  2. Divide each bean into 4 or 6 pieces, cutting them lengthwise at a slant, and place them in cold water with a little salt dissolved in it.

Cook and serve

  1. In a saucepan, bring the water to a boil and add the salt and baking soda.

  2. Add the beans to the boiling water and cook quickly with the lid uncovered, ensuring they do not get smoked.

  3. When the beans sink to the bottom, they are tender; drain them in a colander.

  4. Serve the beans with plain melted butter.

What each ingredient does

Fresh french beans
Form the main body of the dish, becoming tender when briefly boiled.
Plain melted butter
Adds richness and fat, giving the cooked beans a smooth, savoury coating.
Baking soda
Raises the water's alkalinity, which helps the beans keep a bright green colour.

The step that matters

Cook quickly in boiling water with the lid uncovered. Beans need a fast, vigorous boil to cook evenly while keeping their colour. Overcooking softens their texture and dulls the green, so test for tenderness as they sink.
