This is a perfect bowl for a winter day. Khao Poon is a traditional Lao soup with red curry and rice noodles, fragrant with lemongrass and coconut. It’s light, spicy and aromatic, finished with a shower of fresh herbs, bean sprouts and chiles to create a meal in a bowl. While the noodles are cooking, heat the oil in a soup pot. Divide the rice noodles between serving bowls.
