Gluten-Free Cornbread

[mlerules]

Dear LazyWeb ('specially Gluten-Free Folks): I wanna make good gluten-free Cornbread using the recipe from the blue 'n' orange Albers cornmeal box, but don't know what kind of (or how much) flour to substitute for the "1 cup all-purpose flour" it says to use. Plz help me LazyWeb! Thx in advance for yr thoughts, tips, suggestions.

EDIT: Oh, he!! - the box says the stuff's Made On Equipment That Processes Milk, Wheat, Soy & Egg. *sigh* Mebbe I'll give up this whole idea...
