I made two lovely sprouted grain breads recently in the evening, unusuall because I normally bake in the middle of the day. And now I know why I don't bake in the evening too.
I have 3 kids running about in another room adjacent to the kitchen yelling and screaming and doing what they love to do when winding down from school when I put 2 nicely risen loaves in the oven. They were both about 4 inches high and promptly fell to 1 inch high.
They still taste fine, just a wee bit dense though, so I'll make some in the afternoon this week instead :)
