Somebyrd - we had this question a while back - you could do a "Search the Site" to find everyone's answers. If my memory serves me correctly, I believe everyone said you can still buy it at oriental/Asian markets.
Hmmmm tried searching the site but I think having the word "all" in the search throws up way too many answers and I cant find anything related to All Sauce. Ho hum will have to check my local Asain shops (bet I find it over the road LOL!)
