Hi, if you want to find out about ‘Kate’ flour click on to ‘A Merrier World’ in Rose’s list of contacts on the left hand side of the home page, it is about halfway down. That is Kate’s blog and you will find all the information you need about the flour and the processes of changing our flour (I am in the UK too) into something that can be used successfully for Rose’s recipes. I have used the process myself and it does work but you can also use a combination of plain flour and potato or cornflour and get quite acceptable results. As others have said, Rose’s recipes don’t use SR flour, just keep that for your British recipes.
By the way, I have met Kate, and Rose too when she was in the UK two years ago, I’ll never forget the thrill of meeting her, she is a lovely lady! She puts a great deal of thought and care into her recipes, if you follow them carefully you will achieve success as I have, even though I felt flummoxed to begin with, reading about ‘cake’ flour and other strange commodities!
