Explorateur cheese, produced in Ile-de-France, is a triple cream, cow's milk cheese with an edible rind and contains 75% butterfat content. The cheese was created in the 1950's in honor of the first U.S. satellite, the Explorer.
Because the cheese is so rich, a little bit goes a very long way. Like all triple creams, this cheese can be eaten at nearly any stage of ripening. As the cheese ages, its interior with go from a chalky, firm, pristine white to a runny, yellow to beige mass with a much more intense flavor. Each stage is equally delicious served with Champagne or a California sparkling white wine.
