Notes
- Kanten powder is a vegetarian gelatin substitute derived from seaweed. If unavailable, agar-agar can be used as an alternative.
- Adjust sugar quantity based on your preferred level of sweetness.
- Whipped cream is optional but adds a creamy richness to balance the bitterness of coffee jelly.
- Ensure the kanten powder is fully dissolved; otherwise, the jelly texture will be uneven.
- For a stronger coffee flavor, increase instant coffee slightly, but avoid over-concentrating as it may affect gelling.
