Cut a deep cross in the top., Bake the bread for approximately 40 minutes, or until it tests done (a cake tester or toothpick inserted into the center will come out clean)., Remove the bread from the oven, and cool it on a rack. Enjoy warm or at room temperature. Serve with sweet butter and a dollop of marmalade, if desired., Store, well-wrapped, for a couple of days at room temperature; freeze for longer storage.
