Go For Butter Instead Of Milk For Richer Boxed Mac And Cheese
To make boxed mac and cheese richer, ditch the milk and add extra butter. The result will be a bowl that is so rich and creamy that you may even forget that it came from a box.
You could start by adding double the butter called for on the box and adjusting as needed — it may require some trial and error the first time around, but it will be worth it.
If you're worried about leaving out the milk entirely, you can just lessen the amount of milk the box calls for and up the amount of butter, which should give you a similar result.
