ha, does that also make the yolks yellower? i heard they feed something to chickens here to make eggs to use in fettuccine, so they look more yellow and don;t have to add coloring. there's a french cheese that's colored yellow with flowers
But back to butter, isn;t there a (?)medieval tower (or maybe more than one) called the "butter tower" paid for by some butter tax or something?
Yes it does. In fact that's the only thing that determines the color of yolks: the color of the flowers the chicken eats. Since bright orange yolks are quite fashionable, many farmers make their chicken eat bright orange flowers.
