Did you know that pad Thai was invented less than a hundred years ago? And that pizza became popular across Italy only after it was embraced in the United States? This week, we’re joined by author Anya von Bremzen to discuss the unlikely origins of some of the world’s most famous national dishes, from pot-au-feu in France to borscht in Ukraine. Plus, we crack the case on wine fraud with journalist Rebecca Gibb; Dan Pashman de-influences school lunch; and we prepare Thai Salad Rolls.
