Soak gelatine in cold water. Wash the limes in hot water and grate them dry. Rub the skin off one fruit. Peel a long, thin piece of the second lime and cut it into 6 thin strips. Squeeze both limes.
Separate eggs. Beat the egg yolks and 60 g sugar until creamy. Stir in yoghurt, lime juice and grated zest. Squeeze the gelatine, dissolve. Stir in 3-4 tablespoons of lime egg cream, then stir into the remaining cream. Put it in a cold place. As soon as the cream starts to gel, beat the egg whites until stiff and fold in. Pour cream into glasses and refrigerate for about 2 hours.
Wash, clean and halve the strawberries and put them in a bowl. Put 5 tablespoons of strawberries with 1 tablespoon of sugar into a mixing cup and puree finely with a hand blender. Decorate lime cream shortly before serving with strawberries, strawberry sauce and lime strips.
