Today on Bagel Issues, Dave, Nastassia and The Rest answer a bunch of listener questions. Topics include: the mineral content of seltzer and how it affects perceived carbonation, how to improve the insulation of your oven, something about milk punch, and, for reasons I cannot recall, centrifugal birth machines. Plus, a listener question about bagel toppings launches Dave into an extended monologue on how to prepare home cooked salmon, and why hickory smoke powder is the secret ingredient.
