You can try using Arrowroot Powder, Eileen. You can just slightly more than the amount of cornstarch called for (try 2 1/2 tablespoons in this recipe), and it should thicken beautifully. (We don't have this listed as an option because arrowroot is a little bit more difficult to find than cornstarch, but you should be able to order it online if your local grocery store doesn't stock it.) Happy baking! Kye@KAF
