Home-dried fruit

I've been trying out drying fruit in the oven.
The result? The. Best. Dried Apple. Ever.
Tangy and full of flavour, way better than the stuff you buy. (What's up with that? Maybe it's fresher, or perhaps I just used better apples?)

Method:
Peel and slice fruit.
Lay out in a single layer on wire racks in the oven.
Turn the oven on as low as possible (< 90 C). (If you have it too hot the surface seals and moisture from the inside can't escape properly.) Wedge open the door with the handle of a wooden spoon.
Leave for ages until the fruit is leathery and you can't squeeze out any moisture (about 10 hours for the apples).
The Joy of Cooking says you should "pasteurize" the fruit once it's dry - bake at 80 C for 15 minutes.

Granny Smiths - highly recommended.
