LT42 no Kerrygold? The absolute benchmark of butter.
I think I tacitly include it as we all know it is a top tier butter with the others mentioned.
Top tier: Anchor, Kerrygold, Lurpak, Country Life, President (a global traveller like me has to accept whatever is obtainable in the local import store).
2nd tier: Supermarket own brand.
3rd tier: Olivio
Illegal: I Can’t Believe It’s Not Butter, Utterly Butterly, Margarine.
