it's hard to describe...it tastes creamier, a little sweeter, in general more complex. like the difference between a crappy fast food item and its equivalent at a pricey restaurant. i'm sorry you puked up milk -- yuck!

there aren't strict laws about selling unhomogenized milk, but it is extremely rare. i think it's just become normal, so no one questions it? do they have it in australia? here there are often state-by-state laws restricting the sale of raw milk (unpasteurized, unhomogenized) which makes it something of a black market item among the True Believers In The Power of Raw Milk (of which there is quite a growing community). often you have to say you're purchasing it 'for your pet' to get around the laws, so in practice it's not that hard. but in reality, you have to connect personally with farmers in order to buy it, so it's a lot of work. my connection (ha!) has a waiting list with a dozen people on it waiting to get on her weekly fresh milk delivery list -- so far i've only bought frozen from her. but then, i don't know what i would do with a gallon of fresh raw milk every week, so i haven't gone onto the permanent list yet :)
