Here in Utah you pretty much don't get any good fresh produce during the winter months. So, my husband & I have been buying Fresh Tree Ripened Oranges straight from California and selling them. They are SO yummy and such a treat to have. Anyway, we LOVE to can, so... we decided we were going to bottle and dehydrate some oranges. We peeled and separated about 30 lbs. I am a little particular about getting all of the nasty white stuff off the oranges, whereas my husband is not. He did the oranges to be bottled and I did the oranges to go in the dehydrator.
I tried the bottled oranges but could only taste the bitterness of all that white crud. Needless to say I am bummed. I am assuming they would be better but I don't really know that they would be super delicious like I was hoping or worth all the work of peeling, scraping crud, and separating.
The dehydrated oranges were kind of a flop too... they're not good for a treat like dried Watermelon is (oh this is so yummy) they will be good to put in a pot of sweet smelly stuff to boil on our wood burning stove.
The moral to this story is: I don't think I will try preserving oranges again.
