It looks as if you’re having great success with your cooking these days Michele. I remember the days when nothing much turned out for you.
Mab, all Laucke mix flours have salt, sugar and improver included. ( including the Crispy White) Laucke Wallaby flour does not have anything added. Anything that says Bread flour does not have anything added. In my opinion Laucke mixes are the best flour available. Then Wallaby, then the rest. I add improver to all bread flour except Laucke mixes. Mab , hope this help.
