Here is what I have been using for making focaccia in my pizza oven lately. This involves a biga which is a starter slurry you prepare in advance. I like to start this 24 hours before bake time.
Yields 2 12" focaccia
biga
- 1/2 tsp dry yeast
- 4 ounces water, preferably without chlorine (filtered)
- 5 ounces type 00 all-purpose flour
Type 00 is a very fine flour in Italian baking. It handles exceptionally well and lends itself well to an airy focaccia.
