The machine has just produced a loaf of bread that has tried hard to cave in; it obviously did not quite succeed. At least it rose well enough. I am sure it will be very edible.
When you get used to loaves appearing, looking wholesome and presentable, (they sometimes turn out like ski slopes or mini bricks) there is always that little feeling of disappointment, that in spite of my best efforts, the final product does not look quite right. I think I got too complacent. For sometime I have had to change the recommended water measure, as the packs of flour - note plural- required it. It is difficult to predict, (indeed, for me, it is impossible to predict ) how a pack of bread flour will behave till I have seen what it does when transformed into a loaf.
Growth patterns, like too much rainfall, or, drought, lack of warmth, or, sunshine, in essence, Nature's vagaries, all affect the efficacy of bread flour. I think the new bag of flour I used has just reminded me of it.
