Lyophilisé, also known as freeze-dried in English, is a process used to remove liquid content from food items while preserving their shape, taste, and nutritional value In the context of French cuisine, lyophilisé refers to the technique of freeze-drying various ingredients to extend their shelf life and make them more convenient for storage and transportation.
