Beans, Boiled French
Ingredients
Directions
Prepare
Cut off the heads and tails of the beans and remove the strings by slicing a thin strip on each side.
Divide each bean into 4 or 6 pieces and place them in cold water with a little salt dissolved in it.
Boil and serve
In a saucepan, bring ½ gallon of water to a boil and add the salt and baking soda.
Add the beans to the boiling water and cook uncovered, ensuring they do not get smoked.
Cook until tender, about 10-12 minutes for very young beans or 15-20 minutes for moderate size.
Drain the beans in a colander and serve with plain melted butter.

What each ingredient does
- French beans
- Form the main body of the dish and become tender when boiled.
- Baking soda
- Raises the water's pH, helping the beans stay bright green while cooking.
- Butter
- Adds richness and a smooth coating of fat to the cooked beans.
The step that matters
Cook uncovered in fully boiling water. Green vegetables cooked in a rapidly boiling, uncovered pot keep their colour and texture. Covering the pot or adding beans to water that is not boiling can dull the colour and make them soggy, so the beans should go in only once the water is at a full boil.
