This week on Cooking Issues, Dave pays tribute to his recently deceased grandfather, and shares some food-related memories of him. Plus, he and Nastassia discuss his forthcoming book on low temperature cooking, why he always ends up in the middle seat on airplanes, and answer questions about Japanese fish sauce, collagen and meat texture, eliminating off flavors in grass-fed beef, goat cheese, and more.
