Unlike most people who have a nibbling relationship with cheese, Tenaya Darlington (aka Madame Fromage) has an obsession. Three years ago, she began a dairy diary on Blogger, and the rest is fricassee. She can’t leave the house without a cheese valise. Or at least a plate of appetizers. On rainy nights, she likes to invite the rabble in to get rid of the rinds in her crisper. You might find her serving the odd bit of Stilton with a Manhattan, or just a few nubbins with cans of Schlitz. You may have read about her cheese soirees in The New York Times.
