Samuelsson's new book, 'The Rise,' is a celebration of Black excellence in the culinary world — and the many Black cooks who have influenced American food, often without credit. He also talks about converting his Harlem restaurant Red Rooster into a community kitchen during the pandemic, and his roots in both Ethiopia and Sweden. Also, film critic Justin Chang reviews 'The Witches,' an adaptation of Roald Dahl's classic children's book.
