How Much Yeast

ROSE QUESTION: Feedback: I have been attempting to make my deceased mother-in-laws recipe for what they call Norweigian Flat Bread. The recipe that I have calls for aprox. 4 cups of rye flour, 4 cups of white flour, 1 cup of Karo syrup, butter, salt and scalded milk. It calls for one package of yeast. I have trouble getting the bread to rise, do you think that 1 package of yeast is correct? This recipe makes 3 12" circular shaped breads.Thanks for your help!

ROSE REPLY: 4 cups of flour usually require about 1 teaspoon of instant yeast or 1-1/4 teaspoons of active dry yeast. but when you also have a large amount of sweetener and/or butter you need about 3 times the amount.
