About this class
This online oyster class centres on shucking. Lesson #3 opens three sizes, N.0, N.2 and N.4, with the same method, and each gets its own dish: grilled on a Japanese barbecue under a furikake, served with a sea foam, or turned into Grégoire’s signature granité with hibiscus, apple and pickled cucumber.
The other shellfish open and close the class. Razor clams from Scotland are grilled over kombu for a ceviche and served with burnt leek, and New Zealand green mussels are glazed with a cider reduction on the barbecue and served on a chorizo paste.
