NEW YORK (CBSNewYork) – As the saying goes, revenge is a dish best served cold.

You know what else is best served cold? The Peruvian dish, Causa. It’s a potato-based dish, almost like a small cake, typically served either as a small meal or an appetizer.

The Flatiron restaurant Raymi offers up delicious causas ever day, along with many other tasty Peruvian plates.

Chef Richard Sandoval stopped by The Couch to show us how to prepare one of his favorites.
