For Elias, a Sporkful listener in LA, and his former roommate, Paul in Brooklyn, the feud started with an innocent craving for burgers.

“When I started scrolling through an app to place the order [for burgers], Paul was like ‘Oh, but we’re not gonna order [a burger] to deliver,’" Elias (below) recalls.

They spent the rest of the night arguing -- with Elias pointing out the convenience of delivery, and Paul horrified by the toll it would take on their meal.

"On the way to your house, [your burger is] getting destroyed," Paul (below) argues in this week's episode. "You’re going to have a pile of hot garbage -- or cold garbaged, usually -- that is not worth eating."

This week on The Sporkful, Dan and Serious Eats food science guru Kenji Lopez-Alt (author of The Food Lab cookbook) try to help Paul and Elias resolve their burger feud.

“As a piece of hot meat sits in its residual heat," Kenji explains, "moisture from the inside and steam evaporating re-condense back on that surface."

"What you end up with 15 minutes [or] 30 minutes later is very different from what went into that package in the first place," he concludes.

But is it a worse burger?

Listen in to the full episode to hear the verdict. Plus, Kenji answers more of your food science questions -- like: Is duck fat overhyped?
