Put the milk and sugar in a frying pan, bring to a boil and make until the sugar is completely dissolved.
Add both types of cream and just bubble from new.
Freeze the mixture in the ice cream maker or in a large enough bowl and freeze in the freezer for at least 3 hours, stirring regularly with a whisk to make the ice cream creamy.
Crush the raspberries. Stir the lime juice and zest and the powdered sugar into the raspberry sauce.
To serve, thaw the Fior di Latte in the refrigerator for 10 minutes. Then, using a glass spoon dipped in water, cut out balls and arrange in dessert bowls with the raspberry sauce.
This fine ice cream dessert, called “milk flower”, consists mainly of milk, cream and sugar and finds a wonderfully fruity rounding in the raspberry sauce.
