Gelling agent that sets the liquid into a firm jelly as it cools.
Sugar-candy
Adds sweetness and body to the finished jelly.
Cloves
Add a warm, spiced aroma to the liquid.

The step that matters

Reducing to the stated volume. Isinglass is a collagen-based gelatin that sets only when the liquid is concentrated enough. Boiling down to the target volume strengthens the set, and straining while hot keeps the jelly clear as it cools.
