Coffee Jelly
Ingredients
Directions
Prepare the coffee
Roast the coffee over a moderate fire until fine yellow.
Set aside 1 ounce of the roasted coffee.
Place the rest of the coffee in a bowl with 3 cups of nearly boiling water; cover and let cool.
Make the jelly
Boil ½ cup of water and pour it over the reserved coffee; add 1 teaspoon of isinglass.
Once clear, combine this mixture with the cooled coffee mixture.
Strain through a silk sieve.
Mix in ¾ pound of clarified sugar, 1 ounce of isinglass, and ½ cup of kirschwasser.
Serve chilled with ice.

What each ingredient does
- Coffee
- Provides the main flavor and dark color of the jelly.
- Isinglass
- Sets the liquid into a firm jelly as it cools.
- Clarified sugar
- Adds sweetness and helps balance the bitterness of the coffee.
- Kirschwasser
- Adds a distinct aroma and flavor that complements the coffee.
The step that matters
Letting the reserved coffee clear before combining. Isinglass must be fully dissolved and clear before mixing, since undissolved gelatin-like protein can cloud the jelly and leave uneven setting.
