I would imagine you are experiencing the same problem that we in the UK have and that is the difference in the quality of the flour you use. If I use my British recipe books I have no problems but if I try some American recipes I don’t get the best results. This is because of the difference in the protein content of the flour apparently between the two continents, I would think that is your problem also. Hope this helps in some way, I’m sure Rose coud help even more.
