Here is another recipe originally taken from Sam Stern's "Cooking up a Storm". As with most sauces, it can be any of the individual ingredients that contain hidden gluten, a few tweaks later, however, and Sam's delicious recipe is completely gluten free and just as delicious, I actually believe that if you use Tamari rather than Soy sauce it helps with the sticky bit,,,yum. Sam's original recipe says to cook for 1 hour; however, I like my ribs really caramelised and crusty so I normally leave them an extra 15 mins. Delicious with wedges or plain basmati rice but it is equally delicious served as part of a Chinese meal with fried rice such as, Sue Lau's Chinese fried rice Recipe #38748.
