I got the idea for this marmalade from the exquisite book Coming Home to Sicily by Fabrizia Lanza. She passes oranges through a meat grinder instead of the traditional slicing method. And I love the Satsuma orange for marmalade as the peel is not too bitter. For this batch I used 6 cups ground oranges, 6 cups water and 6 cups sugar. Boil the oranges in the water until tender, then transfer to a wide pan and add the sugar. Boil down until it is gelled and then jar. For more info on making marmalade, see this great tutorial.
