In the first episode of our brand-new season of “Weekends with Yankee,” co-host Amy Traverso travels to Boston to follow in the footsteps of culinary legend Julia Child through the memories of some of the city’s most celebrated female chefs, including Lydia Shire, Joanne Chang, and Tiffani Faison. Lydia and Amy visit Savenor’s, Julia’s beloved butcher shop in Cambridge, and later, Amy pays homage to Julia by making sweet and savory Apple, Cheddar, and Caramelized Onion Pastry Bites.
