Marinated orange carpaccio & Aperol granita

For ➍
8 oranges, 4 for serving
2 tbs pistachios, minced
fresh mint
granita:
2.5 dl Aperol
2.5 dl water
200 g sugar
zest of 1 orange
marinade:
2 dl fresh orange juice
50 g sugar
½ vanilla pod
½ ts pink peppercorns
1 quill cinnamon
1 star anise
lemon peel & orange zest for decoration

Prepare the granita the day before. Bring the water and sugar to a boil. Let this syrup cool. Dilute 2.5 dl Aperol and add 2.5 dl syrup. Finish with orange peel and mix carefully. Pour into the ice cube tray and freeze for 12 h.*
For the marinade: bring all ingredients to a boil and let cool in the fridge.
Peel 1 orange per person, cut into thin slices and arrange on a freezer cooled deep plate.
Pour a little marinade over it. Decorate with mint and minced pistachios.

Just before serving, place a scoop (or a nice ball) of granita* over it.

*To make the granita ready for serving, mix lightly in a food processor. Continue with a fork.
The traditional method is to freeze the liquid for 2 h, or until the mixture is frozen around the edges. With a fork, draw ice from the edges towards the centre. Return to the freezer, and then repeat this process about 3-4 times, every 30 m, or until all of the granita mixture is formed of ice crystals. Serve immediately.
