Butternut Squash and Turmeric Focaccia Recipe +9M. Fluffy, airy and addictive. The butternut squash sweet flavor is very well balanced by the sea salt and the rosemary on top. A huge hit with the kids, I had to prepare a second tray to take pictures for the blog :-) It’s not difficult, the dough just needs some time to proof and you don’t need to do anything while it rests!
