What each ingredient does

Pistachio nuts
The main ingredient; blanching loosens their papery skins so they can be removed, leaving pale kernels.
Carbonate of soda
Makes the boiling water alkaline, which helps loosen the nut skins for easier removal.

The step that matters

Boil for a moment, then strain. A brief boil loosens the skins. Boiling too long cooks the kernels, softening their texture and flavour, so timing matters.
