  2. Chop the white cabbage, green sweet pepper (removing seeds and white skin), and onion.

  3. Soak the chopped vegetables in cold water for 30 minutes to reduce strong flavors.

Dress and serve

What each ingredient does

Watercress
Provides the crisp, peppery leaves that form the base and fresh flavour of the salad.
White cabbage
Adds crunchy texture and bulk to the salad.
Green sweet pepper
Adds crisp texture and a mild, fresh vegetable sweetness.
Onion
Adds sharp aromatic flavour to the vegetable mix.
Olive oil
Adds fat and smooth richness that carries the flavours of the dressing.
Lemon juice
Adds acidity that brightens the vegetables and balances the oil.

The step that matters

Soaking the chopped vegetables. Soaking in cold water for 30 minutes draws out some of the strong sulphur-containing compounds in onion and cabbage, mellowing their harsh bite. The vegetables must then be drained well, because leftover water dilutes the dressing and makes the salad soggy.

Swap the onion

How well each one fits the dish's main ingredients (watercress, cabbage, pepper, lemon, olive, celery):
