Try the King Arthur site. I've not had a bad recipe from that site.

Here is a link that might be useful: King Arthur

Thanks for the suggestion, but they have only the one recipe that calls for potato flour, although they do sell potato flour. That is where I got the one recipe I have. They have lots of recipes calling for instant potatoes, but that isn't quite the same thing as flour.

Use your old recipes and substitute potato flour. Below is a table of substitutions. 3/8 of a cup of potato flour equals 1 cup of white flour

1- 3/8 cups barley flour for 1 cup white flour
1 cup corn flour for 1 cup white flour
7/8 cup corn meal for each cup white flour
3/8 cup potato flour for 1 cup of white flour
7/8 cup rice flour for each cup of white flour
1 cup rye meal for 1 cup white flour
1-1/2 cups ground rolled oats or 1 cup oat flour for 1 cup white flour
1 cup whole wheat flour for 1 cup white flour.

What I've done is just substitute some of the regular flour with potato flour.
