i used cottage cheese which probably baked up firmer than cream cheese would. Cottage cheese makes a very good old fashioned pie also. I assumed cornstarch was the starch and it worked fine.

Is it cottage cheese or cream cheese?

You list starch as an ingredient. what starch are you talking about. The only starch I know is cornstarch, and how do you measure 1 There stillis no mention of why it is called a Peat Cake.
