Potatoes need light to chit - my guess is that your pantry is dark - most are - pop them on your kitchen windowsill in egg trays - they'll soon start to chit.
By the way, chitting produces little stalks, not roots. The roots will grow after planting.
Dove, I've a window in the pantry so they've been sat by that. I'll take a photograph in the morning (working v. late tonight) and see what you think regarding their development.
I guess I'm just used to the ones I buy to eat going crazy that this lack of life worries me!
