Have you moved the family to a place where exotic food means the $4.99 Cantonese buffet? Can’t find good Italian arborio rice, Indian besan flour, Mediterranean pomegranate molasses, or Israeli toasted-pasta couscous at your corner store? Here’s one of the benefits of being well-connected: Via www.ethnicgrocer.com, you can purchase all these wonderful foods, plus other hard-to-find delicacies such as pear nectar, sun-dried tomato relish, tandoori paste, and wild-mushroom sauce. The site’s gift baskets also are great for those who have — and eat — everything.
