Perhaps a dumb question, but I've only recently started doing my own bread and I'm generally happy with the results (despite a couple of embarrassing failures).
Until now, I've baked my loaves uncovered until I'm happy with the colour on the "roof", then covered it with foil and continued.
Something I read yesterday suggested the opposite. It said I should cover for the first half then colour for the second half of the baking time.
To be honest, my instinct is to stick to what has worked for me so far, but I'd like to know what you master bakers think!
