Rick is always up for a cooking challenge. After a day spent boating and kayaking on the Sea of Cortez with a local ecotourism group, Rick grills dinner for the group on the beach at Espiritu Santo Island - one of the most biologically diverse marine areas in the world. The waters surrounding the island support coral reefs, colonies of sea lions and more than 500 species of fish. To stock up on supplies, Rick shops in the La Paz market for local cheese, fresh produce and chiles and on the island purchases seafood from a fisherman. Along the way, Rick learns from his guides about flying manta rays, dolphins and the local flora. Then he grills fish and makes a stunning papaya salsa on the beach.
