I have a question about step 5 on the recipe "Sicilian Blood Orange Marmalade" from dymnyno. It says:
"Slice them very thinly and turn and slice the other direction so that you mince the oranges."
I'm not 100% sure if this is what you're asking but the 4th step is just asking you to dice the oranges up into small pieces.
Yes, she wants you to use the orange peel. She says that after the soaking there is no bitterness from the peel.
Yes, dice the whole orange into small pieces and that is what you make the marmalade with. The soaking removes all/most of the bitterness from the peel and the result is a great marmalade....with a little sugar.
