It has been raining here in Napa (hooray!) so I’ve had time for some rainy-day projects, like homemade cottage cheese. I had forgotten how easy it was, and how delicious. Twenty years ago, Sue Conley—the co-founder of Cowgirl Creamery —shared her stovetop recipe with me. I made it then, used it for a story in the San Francisco Chronicle and then forgot about it.
