Before working the cream, make sure you put your equipment (whisk and bowl) in the fridge an hour beforehand, it makes whipping far easier.
Whisk the mascarpone and the cream together in the bowl until they reach a good consistency. That should take about 10 minutes.
Add the sugar in two additions and keep whisking until the cream holds a soft peak.
Chill in the fridge
In another bowl, combine the egg yolks and the sugar (16g)
Whisk until pale
Then fold this mixture into the cream you whipped earlier, gently, with a spatula.
Chill.
