Big Bob Gibson Bar-B-Q Original White Sauce. Since 1925 folks have been enjoying the tangy taste of Big Bob Gibson's white sauce. Friends and family were first introduced to the secret recipe sauce on chicken and pork at weekend BBQ's where boards were nailed to trees for tables. From backyard to restaurants, one thing has remained the same: folks can't get enough of that unique barbecue flavor. This is a National Champion Award Winning BBQ! 1995 American Royal International BBQ Sauce Contest: 1st Place
