So I started to wonder what the “TUC” initials on those yellow-packaged crackers mean ― and was pretty surprised by the results I found, which had absolutely nothing to do with the product.

In a small saucepan over medium heat, melt 5 tablespoons butter. Pour Ritz crackers into a medium bowl, and crush into coarse, uneven crumbs. Pour melted butter over crackers and mix to combine.
