What each ingredient does
- Brussels sprouts
- The main vegetable; cooking softens its firm cell structure until tender.
- Baking soda
- Raises the water's pH, which helps the sprouts stay bright green while they cook.
- Butter
- Adds fat and richness, carrying flavour across the surface of the cooked sprouts.
The step that matters
Cook the sprouts in an uncovered kettle of boiling water with the baking soda for 20 minutes or until tender.. Cooking time decides texture: too short leaves them hard, while overcooking makes them mushy and sulfurous. Keeping the water boiling and the pot uncovered helps the sprouts stay green and let volatile compounds escape.
