Cauliflower is considered a superfood. One serving of cauliflower contains over 75% of the RDA of Vitamin C. It also a good source of Vitamin B6, folate, potassium and dietary fiber...and it tastes good to boot! :-)
Wash your cauliflower well and then core it and cut it into pieces. Many people will tell you to blanch it first but I have dehydrated cauliflower both ways and found NO difference so I would skip this monotonous step. Place the pieces onto your dehydrator trays.
Turn on your dehydrator and dehydrate about 8 hours or until the cauliflower is brittle. To rehydrate, place in a bowl of ice water for 30 minutes and then toss into your favorite soup recipe, casserole, etc. If you are eating cauliflower as a side dish on its own, soak in the iced water for 30 minutes and then place in boiling water for 15 minutes.
