I have read many times about people saving their vegetables scraps/peelings and using them to make vegetable stock.  I take a slightly different approach and dehydrate them to make stock powder.  The end result is the same but I find it easier to make and it takes up minimal storage space.

This is my dehydrator.

I had some broccoli stalks, kale stalks as well as some carrot and onion ends stored in the freezer so I spread them on the tray of the dehydrator and let it work its magic which took about 24 hours.  You need to make sure that the vegetables are thoroughly dried.

This was the result.

I place the dried pieces in the small spice grinder attachment for my food processor and blitz them until they are a fine powder.

I generally store the jar in the freezer as it does not contain any preservatives.  This partially filled small Vegemite jar is the yield from my tray of vegetable scraps.

While I have chickens and a compost heap, it is nice to actually be able to use these scraps and not have to buy packaged stock powder.
