as a fan of Kerrygold, I respect Irish butter. For some reason American butter doesn’t even come close. French, perhaps.
Pretty much all I use butter for is omelets, but that's every breakfast.
The owners own a creamery up in Marin, and they make their own cultured butter in house. At $14 for an 8 oz block it is much more expensive than the stuff at Safeway, but it has a totally different taste.

CH: 3,5% 2,5% fat

I think I can taste the extra fat in the "full" and "drink" grades, but maybe it's better cow welfare and not just the fat?
(direct from a farmer the fat content is over 4%)American milk can't be sold in Europe because of how adulterated it is with hormones and antibiotics. Meanwhile, European dairy products intended for export to the states still have to satisfy European dairy standards.
I bake a lot and I can taste the difference.
