Mo Rocca visits grandmother Genevra Higginson at her elegant three hundred-year-old home in Cohasset, Mass. Cohasset is a coastal village so Mo first digs up clams on a nearby beach and then he and Genevra cook up a hearty, super-fresh batch of clam chowder that they enjoy as a midday snack. The next day, Mo hits the high seas to learn how to pull lobster traps up from the briny deep from seasoned lobstermen. Later, he and Genevra put together a lobster feast using seaweed in its preparation and they make fresh peach ice cream for the Higginson family.
