In a saucepan, add cranberry juice and agar-agar powder. Keep stirring until it has fully dissolved.
Heat it over a medium-low flame. Let it simmer for 2-3 minutes. Then turn the heat off. Allow the mixture to cool down a little. Because if you’ll add alcohol to the hot liquid then it might burn off.
Then pour whiskey and give it a good stir. Pour the mixture in shot glasses.
Add the dried cranberries when the top is around 50 per cent set. So that when you add the berries, they don’t sink to the bottom of the glass.
Refrigerate for 30 minutes or until it is fully set.
Serve chilled!
