These sandwiches are an alternative to the modern grilled cheese. The cheese sauce is similar to velveeta with a little bite to it. And it’s really neat how the egg wash seals the gooey cheese into the sandwich. I think this would be even better if you added a slice of ham before dipping it in the egg wash.
3 tablespoons unsalted butter
3 tablespoons flour
1 cup milk
1 cup grated cheese
1/2 teaspoon Worcestershire sauce
Salt & cayenne
Melt butter in medium saucepan over medium heat. Once melted add flour and whisk to make a roux. Whisk constantly for 1 minute, then add milk whisking constantly. Cook till thickened, then stir in grated cheese till melted. Add seasoning and then set aside to cool.
