People on this board often ask about the availability of various Asian and other ingredients. Check out this page from a web site store called Chefshop. It is a very interesting and eclectic international selection of Asian, European and other gourmet products and ingredients. All are certified kosher by various authorities (I'm no expert on this) and you can read the individual product description for those details. The artichoke spread sounds delicious.
Sorry about the bad link. I hope this one works.
