Was that a typo and it's just 2 cups milk, or 2 half cups so 1 cup total? Our favorite recipe, hands down! I use smoked grueyer and we top it with my husbands pulled pork. Otherwise with 2 tbsp of flour, the bechamel would taste way too floury. Yeah, they mis-typed in the recipe - It should be 2 1/2 (as in 2.5) cups of milk. To the person asking about quantity of milk. This is now my family’s favourite mac & cheese recipe!
