Forrest Murray, Jr. of San Rafael’s Forrest Fire BBQ designed the perfect tribute to his father: Saint Louis-style pork ribs, chicken, and beef tri-tip, cooked low and slow before he pulls them from a wood-stoked barbecue. These are the signature meals he prepares on his Southern Pride Smoker outside Marinwood Market in San Rafael on Fridays, Saturdays, and Sundays, with his mobile catering business and soon at United Markets, San Rafael and Gold Gate Market, Sausalito. Inside a cast iron pan logo of his business rests an outline of the state of Alabama stamped with “928” to reflect Murray’s roots and the date of his dad’s birthday.
