an issue.

Your friend is right about tapping the plates in; they are no good if
they need more than a gentle push to insert them.

Lamello used to have standards on their website to let you know if the
biscuits had gone out of spec.


Although I keep my PC biscuits in a zip-locked bag, I'm concerned that
over the years they may have absorbed some moisture.

Is there any fast/easy/cheap way of drying them out such as baking in
an overn or microwave?

Thanks
