Want to bake the chocolate pound cake from this month's Cuisine. It calls for 1 tablespoon potato starch. I don't have any and can't find any within about 10 miles. Can I use corn starch? or add more flour? Cake flour maybe? (Rec calls for AP flour).
Mel posted results from the pumpkin pound cake from the same article and prompted me to try the chocolate one. (With all of the other pumpkin and sweet potato dishes this week, the wife threatened me if I made one more orange dish...)
