Dehydrated: They are cleaned, not rinsed, and spread over a paper with a gauze fabric. They are allowed to dry in a room with no humidity and constant temperature and once they have done so are stored in a glass jar. To use them, simply rehydrate with water.

In oil: once cleaned, scald for two minutes in boiling water and leave to cool. They are put into a sterilized, some salt is added, with aromatic herbs and olive oil, until they are fully covered.

Marinated: We prepare a marinade and cook the mushrooms in the juice for two to three minutes. It is a well-used conservation method for Robellones.
