There are several possible solutions. Try using less flour (a tsp. less at a time), more yeast (1/4 tsp. more at a time), or less water (a tsp. less at a time). This could also be the result of: • forgetting to add salt to the recipe, •using old flour or the wrong kind of flour for the recipe, •using old yeast, •or using water that is too hot (except otherwise noted in the recipes and for ExpressBake® setting recipes).
