How Now Caramel Cow

What’s new with cows? This week marked the Southern California debut of Horizon Organic Milk from so-called “drug-free” cows. The milk, available at Ralph’s and at natural-foods stores, is described by its makers as “fresh, crisp and clean”--free of pesticides, drugs and growth hormones. But there’s another new milk out there--one that won’t be showing up in natural-foods stores--from the self-described “dairy brand for the ‘90s” . . . Butterfinger. The chocolate-peanut-butter low-fat milk is, however, vitamin-fortified.
