Photo 2 shows you the clumps and the roots where they attach to the "Mother Tuber". You can see there is a swollen area at the connection. This is where I cut to free the new "root tuber" from the "Mother"
Photo 3 shows you the root removed, and the indentation on the "Mother" from where it came.
Photo 4 reveals the tuber, ready for a bath ( I soak them in a pan of water with a touch of chlorox ).
Photo 5, the storage bag. These are perforated zip lock I purchased from Canada some years ago, I am grateful they hold up!
