I've been seeing a lot of commercials for dairy products made with milk from grass fed cows.....is there really any difference in taste or nutrients?
Straight from the udder ... Yes, what a cow eats can affect the taste of the milk.
But after processing ... I don't know.
Yes definitely. I eat a lot of butter. On my steak, blended into my coffee, I cook with it, etc. Generally Kerrygold = the best butter. Plus you can get it anywhere these days.
