Yeah Jerky is easy and as you rightly say, is fine for red meat and fish. However form experience I find the 'Jerk'd' fish can smell after a few days.
Yes the famous fish pie is in there Shewee. Yeah, yeah I know, a couple of years ... <blush>
You can't over-dry anything in a dehydrator. Mice will go hard like grit, but it does come back well due to the surface area.
I always dry most things on a reasonable heat over night and then break it up in the morning, changing tray locations before leaving it low during the next day when out at work.
Smells will cross over if you dry curry on one tray and rice pudding on the other. Hmmm nice
Chicken and Turkey are tough textures when dry and take a very long time to return to something nice and chewy. Poaching seems to be the cooking secret to try and keep as much moisture in as possible.
Fish is very fast and tasty. Prawns can be little bugger though. Veggies even quicker. Raw foods are good too. One particular taste explosion we love is raw Cauliflower and Black Olives. Just slick 'em up and dry them to make a great munchy salty taste when wandering. They always shock people trying them too for the first time.
Pork? Never touch it and don't advise anyone to do it in our book. There's no way of ensuring it hasn't picked up salmonella 'during' the storage process and after having had it one on a remote campsite, I don't recommend it! Amazing how fast you can get out of a sleeping bag and tent when you need to
One of our best puddings/chews/fruit brittal is Rhubarb and Custard. Make as it as you would for pudding and them smear it thinly over the sheet. If you catch it before it goes bittle, then roll it into a wrap, if not then break it into pieces. Another tasty chew.
Anyway, have fun with it. We've had our for 25 years now and have tried most things. Even so we are still learning. For example we are now doing raw liver and raw stewing steak sliced thinly FOR THE DOG
It makes very cheap treats for her which she goes mad for and I'll no doubt make some meals for her, when we take her camping the first time, which beats the current commercial crap on every level.
