When I make scratch pizza, stromboli, calzone, French/Italian bread or focaccia, I use this dough for the bread part. That recipe will make enough dough for 2 large pizzas. When I made focaccia last week for the 4 of us (yielding 2 large squares each), I made a half recipe, using:
3/4 cup lukewarm water
1 teaspoon active dry yeast
3/4 teaspoon salt
1 1/2 teaspoons sugar
1/2 to 1 tablespoons oil (the oil tenderizes the dough, so if you like a chewier crust, use the lesser amount, and if you prefer a softer bread crust, use the greater)
about 2 cups of flour (half white, half wheat is my preference)
1) In a large mixing bowl pour water and sprinkle with yeast. Stir in salt and sugar.
2) Mix in 1 cup of flour and the oil. Add remaining flour, 1/4 cup at a time, until the dough is just a tad bit soft still. If it's too stiff, it's difficult to stretch on the baking sheet.
3) Knead right in the bowl, for about 3-4 minutes. Allow to sit for about 40 minutes.
4) Grease your baking sheet.
5) Punch down dough. Stretch onto the prepared baking sheet.
Focaccia is more of a bread than a pizza crust. You'll want to press the dough out until about 1/2-inch thick all over, as opposed to stretching a pizza crust as thin as you can get it without tearing. Dimple the top of the crust with a fingertip.
6) Allow the pressed dough to rise at room temperature for about 30 minutes.
Now for the topping part.
