Each week on Cooking Issues, Dave solves your cooking dilemmas with his mile-a-minute stream of knowledge. Got a question on ike-jime, the Japanese fish killing technique? We got you covered. Hydrocolloids, sous-vide, liquid nitrogen? No problem. Have a question about pimping your oven to make great pizza? Give us a call. Occasionally Dave will invite special guest chefs, bartenders, authors and columnists to join the show.
