This is Mill Street Radio from PRX, and I'm your host, Christopher Kimball.

Today we travel to Mexico.

Rick Martinez shares the salsa that changed his life.

I'd never seen anything like that.

We also uncover the surprising history of avocados.

You know, before corn, people were cultivating avocados.

All that beautiful pepper juice dripped to the bottom of that little bag, and that's money.

It's like pepper au jus.
