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.
The interior of the truffle is perishable, and the candy will only last a week or two in the refrigerator. Fudge can be kept much longer, as long as two or three months, if it is stored in an airtight container at room temperature. Chocolate-covered nuts, pretzels and various types of brittles can also be kept at room temperature in an airtight container for several weeks or up to a month.
