While the teachers would wax lyrical about the importance of precision, I advocate a more liberal approach. These galettes don’t require blind baking or the fiddly lining of a pastry ring, just casually fold up the edges to encase the filling of your choice. As a little ode to home, I like to use a mature Cheddar. Those Frenchies may know their pastry, but you can’t beat a bit of British cheese.
