A couple of years ago my mother told me that her father (a truck farmer) used to pick satsumas and put them in baskets that would fit under their bed. The beds back then were very high off the floor and the matress was made out of moss. That was how her dad stored some of his citrus. She remembered eating those satsumas for a "long time" after they were picked, but you had to cut them open with a knife in order to eat them as the skins got really hard. She told me about this practice after I told here that I was experimenting with figs. LSU Gold figs will improve in flavor after they are picked if you let them sit out on the counter for a few days.
Sooooo, last season I tried that out for myself. And yes indeed it does work. I picked several small baskets of satsumas, oranges, and grapefruit and put them on a wire shelf that I have. What happens is those citrus will gradually lose moisture through the skin and begin to shrink. The skin will get real hard and you will not be able to peel them like mom remembered.....not even the satsumas. They will not rot or mold as they cure. And you will indeed need a knife to slice them open when you get ready to eat them.
Now here's the really NEAT PART...........as they shrink the sugars and flavornoids that are inside of the juice will CONCENTRATE in both sweetness and flavor....like LSU Gold figs will do. Their taste will be much better than if there were not aged in those baskets. Owari satsumas develop a fantastic flavor when treated this way. Pink grapefruit develops a whole new dimension in flavor,
Soooo, in my area you can pick Owari satsumas late in the season, cure them as described, and still enjoy eating them in early March long after they are no longer available on your tree. And they will be sweeter and have a terrific new taste dimension to boot. You cannot do this with Armstrong satsumas because they do not store very well even on the tree. They will get real puffy inside if kept on the tree too long. Owari does not do that and the fruit can stay on the tree much longer.
Funny thing is.......this citrus storage practice that my"old timer" ancestors knew about was almost lost to my generation if mom had not casually mentioned it to me one day in one of our conversations!!!
Those of you who grow satsumas.....give it a try next year and treat yourself to a new "old way" of eating citrus and extending your season. Too, you will not believe how good they taste when they are first treated in this manner.
