Smoked cheese is any cheese that has been specially treated by smoke-curing. It typically has a yellowish-brown outer pellicle which is a result of this curing process.
Smoke-curing is typically done in one of two ways: cold-smoking and hot-smoking. The cold-smoking method (which can take up to a month, depending on the food) smokes the food at between 20ð and 30ð C (68ð and 86ð F). Hot-smoking partially or completely cooks the food by treating it at temperatures ranging from 40ð to 90 ðC (104ð to 194ð F).
Another method, typically used in less expensive cheeses, is to use artificial smoke flavoring to give the cheese a smoky flavoring and food coloring to give the outside the appearance of having been smoked in the more traditional manner.
Some smoked cheeses commonly produced and sold include smoked Gruyère, smoked Gouda (rookkaas), Provolone, Rauchkäse, Scamorza, Sulguni, Oscypek, Fynsk rygeost, and smoked Cheddar.
