I have an Excalliber dehydrator and have just done a batch of spicy jerky and 2 whole pineapples - if you have not tried dehy pineapple you have not lived!
Just cut the pineapple into 1cm thick (max) slices and dehydrate until nice and dry/toffee concistency ... mmm!
My Spicy jerky varies every time - this one was marinaded in a mix of tomato paste, soy sauce, worcester sauce, ginger, garlic flakes, black pepper , chili powder, malt vinegar and salt for 12 hours then in the box for as long as it took
I too prefer to make meals from dried ingredients rather than dry out whole meals - after all pasta and rice are dried already!
I do a fair bit of fruit leathers for snacks (bananna and strawberry is great!) but Kiwi just goes gritty!
