  2. Let it stand in a cool oven (300°F / 150°C) overnight.

  3. Strain off the liquid without pressure the next day.

What each ingredient does

Elderberries
Provide the fruit flavour and colour that give the ketchup its character.
Vinegar
Acts as the preserving and acidic base that extracts flavour from the berries.

The step that matters

Strain without pressure the next day. Pressing the berries forces solids and pulp through the strainer, which makes the liquid cloudy. Letting it drip on its own gives a clearer ketchup.
