When I lose cheeses in the back of my fridge, they rarely emerge the better for it. Once or twice, I’ve unintentionally improved an uncut wheel by forgetting I had it, but I generally prefer to leave the aging to the experts. Even they can be surprised by what happens. The Swiss cheese pictured above was a happy accident. Wheels misplaced in the creamery’s cellar and discovered months later had evolved in spectacular fashion. The cheese didn’t get dryer, as one would have expected. It got creamier.
