A fougasse is a French focaccia, often cut into elaborate shapes for more crusty surface area. If you are in the area of Kittery, Maine, you can find excellent full and half-size fougasse at Beach Pea Bakery that you would be proud to bring to any family event.
You can make it yourself, if you have a few hours to allow time for the dough to rise; baking takes under 30 minutes. If you want to do the traditional sourdough version and you don't have a starter, you can make one but it takes a few days to get really active, or you could try the Biga Starter, which is ready in a day.
The cuts are important. They serve to provide more crusty surface for the bread. This bread is not a light, airy load, it's all about the olive oil and salt and other flavors that you include. It's great with wine and cheese.
