There isn't as wide of a selection of boxed mac and cheese here.
My favorite food is boxed mac and cheese. It may not be glamorous, but this is my truth. US supermarkets carry many different brands, so it's easy to find flavors like white cheddar, Alfredo, or sharp cheddar — as well as vegan and organic options.
I've encountered just three different brands of boxed mac and cheese (aka "cheesy pasta") in the UK, and almost no store carries more than one.
I've tried them all, and they're just variations of orange cheddar and elbow noodles. And for some reason, at least to me, the cheese powder smells like sweat.
When I visit America, I buy about 30 boxes of white-cheddar mac and cheese. I give the pasta portion to my mother and take the cheese-powder packets with me to the UK.
I'm not proud. I'm just trying to survive.
