Clean, wash and drain the berries (except for a few currant panicles for decoration). Whisk the egg yolks with 80 g sugar in a stainless steel bowl. Add Marsala and whisk over a hot water bath with a whisk until the mixture has become frothy and thick.
Pour the zabaglione into dessert glasses, spread the berries on top. Moisten currant panicles and sprinkle with 1 teaspoon of sugar. Place the currant panicles on the rim of the dessert glass. Decorate with balm leaves.
