If we have broccoli and I don't make this sauce, Hailey wants to know "WHY?". This is kind of adapted from my Mom's cheese sauce. I also use this sauce for, The Best Lobster Casserole, recipe #412590 and Mom's Chicken Wiggle, recipe #366214. I use the block cheese and grate it myself, you could use a milder cheddar if you prefer. BE SURE to thicken the milk mixture with the roux (roo) before you add the cheese or you will have a curdled mess.This keeps for several days in the fridge so don't toss the leftover sauce. I like it cold from the fridge on crackers or as a dip for raw veggies, too.
