7 satsumas/tangerines/mandarins/whatever you call them, squeezed
4 tbsp lemon juice
1 orange rind cut into small pieces
2 tsp vodka
2/3 cup heavy cream
1 cup sugar
dash of salt
(the recipe I found just called for fresh squeezed orange juice. I do not have a juicer so I hand squeezed them.)
Rub sugar and rind together until sandy and damp. Whisk in salt, juices, and vodka. Strain through a mesh sieve. Chill 2-3 hours in the fridge or 45 minutes in the freezer. Try not to let it ice over.
All I did then was blend the juice mixture and the cream for a minute or so to make it all frothy. For consistency, and I plan on doing this the next time I make it, I'd try whipping the cream into soft peaks before tossing it all in the blender.
I'm pretty sure it can be made without vodka but it won't be as smooth. In the end, you can't taste it but it makes the flavor richer and keeps it from freezing solid.
