You mean in them? What else would they have?
Yeah, in them. It's not common here to use butter on sandwiches (though it is in my house).
After maybe five British-made sandwiches, I finally deconstructed one to see what the unexpected creamy/greasy texture was, and found a layer of butter on each piece of bread.
After that, I started pulling all my sandwiches apart. Butter...check. Butter...check. Everything had butter on it.
I even had a discussion with a coworker who had a British wife, and we were both laughing over the sandwiches, why they were so much better: "It's the butter! They always have butter on them! Have you ever had a sandwich with butter on it before you moved here? Me neither! Butter!"
Many years later, I mentioned it to my mom, while I was making a sandwich, and I said, "Take a bite of that and tell me what you think."
Without missing a beat, "It has butter on it. Your grandmom used to always butter her sandwiches."
"What?!?! Why didn't you butter our sandwiches when we were kids?!"
She shrugged her shoulders and said, "Six kids. No time."
