Honestly, i’ve always approached this question the reverse of how it’s posed here. Pretty much every store brand whatever is just fine.
But, picking a few fancier versions of things as exceptions is nice sometimes.

Lately for me, Kingdom aged organic cheddar and Kerrygold butter have been my indulgences. I don’t eat much dairy, so they last me a long time. They’re loaded with flavor. And, it’s just nice to have a few things that feel special.
