Italian Potato Focaccia Bread Recipe. This moist bread is a staple in Italy's Pulgia area (the heel of the boot). The recipe uses potato and lots of olive oil to keep it moist on the inside, and especially crisp on the outside when toasted. Add your favorite ingredient to this basic focaccia recipe to make your favorite version. Maybe rosemary and garlic, leek, or sun-dried tomato and Parmesan cheese? You won't ever buy focaccia bread from the store again.
