Why is Thai food so popular in the United States? We turn to Professor Mark Padoongpatt, author of Flavors of Empire: Food and the Making of Thai America for some surprising insights. We revel in regional Thai flavors with Austin Bush, author of The Food of Northern Thailand, and Leela Punyaratabandhu, author of Bangkok. Chef Hong Thaimee of NYC’s Thaimee Table gives us an essential lesson in a vital Thai recipe, homemade curry paste. Plus, America’s Test Kitchen puts coconut milk to a taste test and tells us about their favorites.
