 I'm Christopher Kimball from Milk Street Radio. This 4th of July, we're pulling out all of the stops. The secret to grilled corn, the world's best mustard, and the hot dog history lesson no one ever gave you. This theme of hot dog danger runs right through, from the Middle Ages, by the way, right through to now. It's the July 4th show coming up this week on Milk Street Radio from PRX. That's this Saturday at 4 p.m.
