I'm looking for what Portmeirion is calling a "breakfast cup," a pretty teacup that's not too tiny, like at https://www.portmeirion.com/60830.html , which is blissfully (for me) made in England:
-- and when I looked for a breakfast cup in general, I learned there's such a thing as a
breakfast table
breakfast pillow
! Who knew?! Well, obviously, many people, but not I. And then, as I touched on ages ago somewhere on this site!, if you look for
breakfast set
say on Etsy, you'll see all sorts of fascinating ideas for your morning comforts, from various cultures!
