As usual, the Iowa State Fair in August will boast of a butter cow. That’s a 600 pound butter cow, mind you. This year, Sarah Pratt, butter sculptress, is providing company for the cow in the shape of a butter Harry Potter. The butter gets reused each year until it goes bad, so parts of Harry could be constructed out of last year’s butter Superman. Back in the 1950s they also made lard pigs.
