Wash and clean the strawberries and cut them into small pieces. Simmer strawberry pieces, jam sugar and lemon juice for about 2 minutes while stirring. Remove from the heat, pour into a bowl and let it cool down while stirring occasionally.
Beat the eggs, egg yolks, vanilla extract and sugar in a bowl over a hot water bath until light and creamy. Slowly stir in the mascarpone and milk and then drain into a bowl over a hot water bath to form a rose.
Put the cream in a bowl and let it cool down while stirring occasionally. Cover ice cream and freeze for 2-2 1/2 hours. Stir every 30 minutes with a fork.
Work half of the strawberry jam into the ice cream mass, so that a marbling is created. Cover the ice cream again, place in the freezer for another 4 hours, while stirring twice more with a fork.
Cut the ice cream into balls and serve in waffles together with the rest of the strawberry jam.
