This is especially helpful when you’re spreading on a softer bread, so as to not have it crumble and tear. Secondly, mayo has a higher smoke point, meaning it won’t burn as easily as butter does. And lastly, the oil and egg found in mayo causes the bread to brown nicely and gives the crust a creamy flavor.
