What each ingredient does

Fresh raspberries
Supply the main flavour and the juice that forms the syrup base.
Sugar
Adds sweetness and body to the juice, balancing the tartness.
Tartaric acid
Adds acidity that brightens the flavour and helps preserve the syrup.

The step that matters

Add the sugar after straining. Sugar is added to the strained juice by measure, per pint. Stirring until fully dissolved prevents grains settling at the bottom of the bottle and keeps the syrup evenly sweet.
