Freeze Drying Biscuits and a Rehydration Test

Freeze drying some ready-made buttermilk biscuits then doing a rehydrating test.
This is part of our Freeze Drying The Alphabet from A to Z series.
Rehydrating starts at 5:26
The biscuits we used were "Bridgford Old South Buttermilk biscuits 3 inch" We got them at our local Smart Foodservice store.
