Potato Focaccia Dough

Ingredients
2 Teaspoons Instant Yeast
1 Cup Mashed Potatoes
1 1/2 Cups Warm Water
4 - 5 Cups All-purpose, Unbleached Flour
1 Teaspoon Salt
6 Tablespoons Olive Oil
Topping Of Choice

Method
In a large bowl, combine the flour, salt, yeast, olive oil, potatoes and half the water.
Mix thoroughly with a wooden spoon, adding as much additional water as is needed to create a shaggy dough.
Transfer to a floured work surface and knead by hand for a few minutes or until smooth.
Place in a well oiled bowl, cover with plastic wrap, and let rise until doubled, about 1 hour.
Preheat the oven to 425 degrees F.
Punch down and place on an oiled baking sheet, forming into an oval or circle.
Dimple the top surface with your finger tips, and then add your topping of choice.
Bake about 20 minutes or until golden.
Serve warm or at room temperature.
