Select the berries and sprinkle with sugar. (Frozen berries also sprinkle, defrost and let stand). Leave to infuse for at least 30 minutes. In the meantime, carefully wash 1 lime and grate the peel. Squeeze the juice out of all limes. Stir cream cheese, quark, 8 tablespoons lime juice and zest, vanillin sugar and icing sugar until smooth.
Pour into a piping bag with a large perforated spout. Pour portions directly onto dessert plates. Spread the berries on top. Chop the pistachios finely and sprinkle over them
