Soak gelatine in cold water. Wash the currants (put 1 panicle aside for decoration) and remove the berries from the stems. Bring the fruit and 1/4 litre of water to the boil.
Add 200 g sugar and simmer for about 10 minutes. Pass through a sieve. Squeeze the gelatine and dissolve in the hot juice. Pour into a bowl and chill for about 3 hours. Whip cream until stiff for serving.
Let the remaining sugar trickle in. Fold in the egg liqueur. Serve the jelly decorated with the panicle and mint.
