  3. The next day, strain the liquid without pressure.

What each ingredient does

Elderberries
Provide the main fruity flavour and colour of the sauce as they steep in the vinegar.
Vinegar
Acts as the solvent and acidic base that extracts flavour from the elderberries and preserves the sauce.

The step that matters
