Old Time Chinese Restaurant Sweet

In many Chinese Restaurants of my youth in New England, it was typical that at the end of the meal along with check and fortune cookies came a delectable sesame coated jelly candy. These fresh fruit (perhaps agar) 1" cubes were coated in toasted sesame seeds and devoured by the six kids in my clan. So much for distant memories of the Hong Fong (up one flight) on Pleasant Street in Downtown Worcester. Since then those candies have disappeared from the table. For a decade or so I could find them at Ho Yuen Bakery in Boston. Now I can only get mass market sort of petrified versions. Does anyone know what happened to these regional courtesy treats? Can someone make the folks at Ho Yuen fess up?
