Shortenning for butter?

I know this is quite pathetic, but I am moving in a week. Dont want to buy too many groceries..so I want to make Kraft Mac and Cheese (yes, I know very white trash of me!) but I have a craving…and I dont have butter…wondering if I can add shortenning instead…

Is there even a big difference between butter, shortenning, and margarine…

Behind the shorterning dabba u will have instructions on how to substitute it for butter...you usually add some water too. But it will lack the salty taste and aroma of butter. With margerine you get the salt but not the same taste. Don;t know how important that is to you. I love salted butter both the aroma and taste.
