Ingredients
- 1 cup boiling water
- 1 cup cold water
- ⅓ cup brown sugar (50 g for extra caramel notes; substitute with white sugar, demerara, or raw sugar)
- 3 tsp gelatin powder (9 g / 0.31 oz)
- 2 tbsp instant coffee (8 g / 0.28 oz; see notes for substitutions)
- Thickened cream or heavy cream (substitute with whipped cream)
- Chocolate shavings

- Fresh mint leaves
- Cocoa powder

Instructions
- Step 1: In a large jug, combine the instant coffee, gelatin powder, brown sugar, and boiling water. Whisk thoroughly until the sugar and gelatin are completely dissolved, ensuring no gelatin sticks to the bottom.
- Step 2: Pour in the cold water and whisk the mixture again to blend everything evenly.
- Step 3: Pour the coffee jelly mixture into dessert cups or a glass dish.
- Step 4: Optional: Use your whisk to gently break any large bubbles around the edges for a smooth finish once set.
- Step 5: Place the jelly in the refrigerator for at least 3 hours to set. The cold water cools the mixture enough to refrigerate it immediately.
- Step 6: If set in a dish, cut the jelly into cubes and transfer them to serving dishes.
- Step 7: When serving, add your choice of garnishes such as cream, mint leaves, chocolate shavings, coffee beans, maraschino cherries, or a dusting of cocoa powder directly on top and enjoy!

Storage
Store coffee jelly covered in the refrigerator for up to 3 days. Keep garnishes separate and add just before serving. To reheat, allow to come to room temperature; however, this dessert is best enjoyed chilled.

Notes
- Use high-quality instant coffee for the best flavor. Substitutes can include brewed espresso reduced to a concentrate but may affect setting.
- Brown sugar adds caramel notes; white sugar or raw sugars can be swapped but alter the flavor profile.
- The gelatin powder quantity is crucial to achieve the perfect jelly texture; avoid substituting with agar agar.
- Thickened or heavy cream works best for richness; whipped cream can be used as a lighter topping option.
- If you want a vegan version, try using agar agar as a substitute, but note texture differences.
