What do stilettos have to do with sundaes? Not much, unless you’re at Arethusa, a Connecticut farm and dairy from the 1860s that was rescued from golf course developers by Manolo Blahnik executives Tony Yurgaitis and George Malkemus. This spring, the couple opened an outpost of their country-chic creamery on Yale’s Campus; it serves dense, pure-tasting ice cream in straightforward flavors like coffee, chocolate, strawberry. The secret is the milk, which comes from Arethusa’s cows, a pampered herd that eats grass, sleeps on mattresses, and enjoys daily tail shampoos. (Yep, you read that right.)
