In the rainy season biscuits and other dry goods become wet under their packing. Can they be recovered?
Just put them in the oven at 100 °C (212 °F, the boiling point of water) and all the humidity will dry out naturally.
The time depends on the size and amount of water in the biscuits:
- smaller and damp: 5 minutes
- large and very wet: up to 20 minutes.
