Raspberry Syrup
Ingredients
Directions
Prepare the juice
Pick and clean red or ripe raspberries.
Mash the raspberries and place them in a pan in a warm spot for 2-3 days to ferment.
Draw off the juice and filter it through blotting paper.
Make the syrup
In a pot, melt 2 pounds of sugar with the raspberry juice over low heat, skimming off any foam without boiling.
Once it reaches a pearl stage, strain it through a cloth, let it cool, and then bottle it.

What each ingredient does
- Raspberry juice
- Provides the liquid base and the fruit flavor of the syrup.
- Loaf sugar
- Sweetens the syrup and thickens it as water evaporates during cooking.
The step that matters
Melt the sugar over low heat and stop at the pearl stage. Gentle heat dissolves the sugar without scorching it or boiling off too much liquid. Skimming removes foam that would cloud the syrup. Stopping at the pearl stage means enough water has evaporated for the syrup to set to the right thickness as it cools.
