Dan Boyce from Montana Public Radio calls in to recommend a novel way to prepare a peanut butter and honey sandwich, plus a caller in Ottawa extols the virtues of day-old popcorn, and a woman who lives in China offers a semantic rant about macaroons and macarons. Photo: Flickr CC / ladylinoleum

Here's a thoughtful approach to sandwich-to-mouth delivery from Eater Jeff in San Francisco (along with Jeff's above demonstration photo): Little is it known that the perfect sandwich grab is actually not a two handed grab (originally designed to accomplish minimal mass of sandwich acceleration), but a one-handed, open palmed, finger-sprawled and action-ready hand arrangement. The palm is placed on the side near the

We examine the ingredients and construction and explain which ingredient is most like Kevin Spacey in The Usual Suspects. Sculptor Claes Oldenburg comes up too. That's his work "Giant BLT" in the video here. Interestingly, the sculpture comes in several parts, so whenever it's installed for display, the curator must make a BLT sandwich,

NPR science correspondent and Radiolab co-host Robert Krulwich joins us for this landmark meeting of the minds. We cover scientific principles including force = mass x acceleration (as in "How do you construct a sandwich that will withstand the force of the bite, without having the mass of the sandwich accelerate out the back?") and the Pythagorean theorem as it
