Oh yeah, the yellow European style butter was a revelation when I found out about it. It tastes way better and is less watery than the pale American butter.
I never heard of filtered milk. Milk is milk for the most part, but once I made the mistake of buying it on clearance. Grabbed it without looking because the price for a normal gallon freaked me out. It wasn’t spoiled, but it was super watery and had a weird color.
