SNIP
The freeze-thaw cycle is really what does it. I laugh at people who
think orange peels can not be composted. A few cycles and they are set
to go. Winter kitchen scraps are usually fully composted by May in
Michigan.

As I understand it, the objection to citrus peel is not that it won't
compost, but that the pesticides used on it create a problem later, or
affect your degree of organicness. At least that's the feeling in Europe, I
don't know about US.

I have to admit I've added it on occasion and no problems that I know of.
