Soak the gelatine. Cover the bikuit with a springform ring and sprinkle with coconut liqueur. Roast 50 g grated coconut and sprinkle on top. Separate the eggs. Mix cream cheese, egg yolk, yoghurt, sugar, remaining grated coconut, lime zest and juice well.
Squeeze out the gelatine, dissolve and fold into the cream. Beat the egg whites until stiff and fold into the cream. Pour the cream onto the sponge cake base and smooth it down. Refrigerate the cake for about 2 hours.
Wash the limes, grate them dry and cut them into very thin slices and place them on the cake before serving. Results in about 12 pieces.
