French Beans
Ingredients
Directions
Prepare the beans
Gather young French beans and peel them to remove the delicate fiber.
Nip off the ends of the beans.
Cook the beans
Bring a pot of water to a boil and add baking soda, salt, and sugar.
Plunge the beans into the boiling water and cook until tender.
For better color, place wood ashes in a cloth and strain the boiling water over it.
Alternatively, steam the beans in a vegetable steamer until tender.

What each ingredient does
- French beans
- The main vegetable, which turns tender and crisp-textured when briefly boiled or steamed.
- Baking soda
- Raises the water's alkalinity, helping the green color of the beans stay bright.
- Sugar
- Adds a mild sweetness that balances the savoury flavour of the beans.
The step that matters
Cook the beans until tender. Green beans turn dull olive and mushy when overcooked, because prolonged heat breaks down the chlorophyll and the cell walls. Check them often and stop as soon as they are tender.
