Triple-crème cheese by John Spottiswood.

These cheeses are the gelatos of the cheese word--incredibly creamy and decadent, thanks to a high butterfat content that comes from tripling the cream. They have roughly twice the fat as a typical Brie or Camembert, but they're much more buttery and rich. Some triple-crèmes are fresh, like mascarpone. Others are soft-ripened, like Boursault, Castello Blue, Brillat Savarin, and Explorateur.
