Strawberry Jelly

Ingredients

Directions

Prepare the juice

  1. Mash the strawberries in a pan using a wooden spoon or potato masher.

  2. Place a sieve over another pan and line it with thin muslin.

  3. Strain the strawberry juice through the muslin.

Make the jelly

  1. For every pint of juice, add 1 pound of sugar and ¼ ounce of dissolved isinglass.

  2. Heat the mixture until the sugar dissolves and boil until it reaches a jelly consistency.

  3. Pour the jelly into glasses while warm and cover them once cooled.

What each ingredient does

Strawberries
Provide the flavour and the juice that forms the body of the jelly.
Sugar
Adds sweetness and helps the jelly hold its set once boiled.
Isinglass
Gelatin-like protein that sets the juice into a firm jelly as it cools.

The step that matters

Boiling to jelly consistency. Boiling concentrates the sugar and dissolved isinglass so the mixture sets firmly when cooled. Boiling too briefly leaves it runny, while overboiling can make it stiff and dull in flavour.
