There's even a gluten free Bisquick out there now, but I have no idea if it's any good since I'm several sacks ahead of my next purchase.
Tip on cornbread. When you use any of the old recipes where they don't add wheat flour all you have to do to keep it all together is make it in a single pan, then just cut off blocks as you eat it.
I like the cornbread recipes where a can of creamed corn is added, it’s so moist.
