Blues rock started with rock musicians in the United Kingdom and the United States performing American blues songs. They typically recreated electric Chicago-style blues songs, such as those by Muddy Waters, Jimmy Reed, Howlin' Wolf, and Albert King, at faster tempos and with a more aggressive sound common to rock.
Vinegar-based condiments, such as mustard, relish and horseradish, keep for 12 months or until the expiration date in unopened jars in the pantry. An open mustard container can still keep for 12 months if you store it in the refrigerator, but it can spoil within one month if you keep it at room temperature. An open container of relish lasts six months refrigerated and should not be stored in the pantry.
Unopened vinegar and oil dressings, like balsamic vinaigrette, will stay fresh for up to four months past the written expiration date. For the most part, this will give the unopened bottle of dressing a shelf life of one or two years, if kept in a cool dark place, like your pantry or cellar. Once a bottle of salad dressing is opened, the shelf life diminishes rapidly. Creamy dressings can be kept for up to four months in the refrigerator, and oil and vinegar based dressings should be consumed within six months.
