According to Le Crem de la Crumb, I used the wrong cheese in my soup last night. I think the soup is fabulous, but, come to think of it, it might be a little gritty seeming. (I’ll still eat it!)

“DO NOT use preshredded cheese, please grate cheese from a block! Cheese that comes already grated is tossed in a powdered coating that causes it to melt differently than fresh-grated cheese and will give your soup a gritty texture. Use freshly grated cheddar and Parmesan cheese!”
