Report Abuse. 1  Engine Backfire On Deceleration. 2  assuming that you are speaking of aircraft engines, here's another angle: 3  That would be Detonation.  It is possible the EVAP is related to your backfire 1  concern. Sounds like your getting too much fuel.
Just about anything can be dried, from vegetables and fruit to meat and fish. Home dried herbs are a fraction of the cost of store bought herbs. Natural fruit leathers are also quite expensive in the store, and are one of the simplest things to make in your dehydrator.
Of course it makes sense to have them in your food storage too. Canning or freezing onions changes the texture and taste, but dehydrating them then re-hydrating them when you're ready to cook is like having fresh onions. I can't tell that they have been dehydrated when I cook with re-hydrated onions.
