Guest Chef: Jeremy Sewall. The herb coriander is native to Asia, but has become one of the most widely used herbs in the world. Paired with licorice-scented fennel, you've got an aromatic combination of flavors that are unique in any dish. Ming starts the meal by making Crispy Pita Chips with Fennel Fondue followed by Shaved Fennel Salad with Coriander Crusted Ahi Tuna. Finally, guest chef Jeremy Sewell of Boston's Lineage takes today's masters to make New England Shellfish with Toasted Coriander and Fennel.
