We’ve been using arrowroot powder for gravies since my mom got the idea from Graham Kerr.
It also is gluten free and my son recommended it to a guy he worked with who had celiac and they gut told him that he now basically got his life back. He could eat Montreal Fries again.
My son has celia - he can’t even use a knife that’s cut bread without breaking out. So I’ll have to tell him about the arrow root powder - where do you find it?
