                                            thin (less than 1/8 inch) slices Gruyère (about 3 by 2 1/2 inches; about 3 oz total; see cooks’ note, below)

Preheat oven to 250ºF with rack in middle. Line a large shallow baking pan with liner and arrange Gruyère slices at least 2 inches apart in pan. Bake until cheese is pale golden, 15 to 20 minutes (slices will firm but will not become brittle-crisp). Cool crisps in pan until firm enough to remove, 3 to 5 minutes, then carefully transfer to paper towels to absorb excess oil and cool completely.
                                         
                                    
                                
                             
                        
                    
                    Cooks’ note: - Trim rind from a block of Gruyère (at least 8 ounces) before slicing on a meat slicer, or ask the deli department to trim and slice cheese. (You can also use a cheese plane to slice the cheese.) The slices may vary slightly in size; what is most important is that they are the correct thickness.
 - Crisps keep, layered between sheets of wax paper in an airtight container, at room temperature 3 days.
