This week on Cooking Issues Dave Arnold is joined by Chris Young, one of the authors of Modernist Cuisine. But first he takes on your questions on blue fish and ike jime, enzymatic peeling, and how to avoid Botulism when you are doing your own canning. Later Chris and Dave get nerdy on evaporative reduction and the Gastrovac. Also don't miss Chris talking about his ventures with Nathan Myrhvold and the Gates Foundations in sub-Saharan Africa in trying to create a reliable fresh milk supply chain that they call East African Dairy Development. This episode is sponsored by The Modernist Pantry that is giving away a free sample of Pectinex when you listen for the code in this episode!
