"In the world of burgers, the In-N-Out vs. Shake Shack rivalry is the stuff of legend, pitting east coast against west coast in a battle of patty supremacy. But rather than feed the fire of an old flame, Alvin Cailan is teaming up with YouTube legend Andrew Rea (Binging With Babish) to teach people how to make both of these iconic burgers at home. Better yet, they've devised the ultimate peace treaty: a Double Shack x Double-Double Animal-style Voltron burger. It's a moment in burger history you won't want to miss."
