Maybe you could just call? I just read an article somewhere that rated butters and if I remember correctly Kerrygold was their top pick. Plugra butter is excellent, if you can afford it - it's SUPER pricey! Just FYI, I use Kirkland and Sams's Club unsalted butters in my FMBC (very similar to IMB, but with whole eggs) and it turns out perfectly every time.' Good Luck!
