For the best flavor, allow the dressing to chill in the refrigerator for at least 2 hours before serving to allow the flavors to meld. The flavor improves even more after 24 hours! Store the Roquefort Dressing in airtight glass jars or containers in the refrigerator for up to 1 week. Consider using a high-quality mayonnaise for a richer, more flavorful dressing. Adjust the amount of Roquefort cheese to suit your taste. For a milder flavor, use less cheese; for a bolder flavor, use more.
