Many years ago my mom bought great Knishes from I Katz Deli in Haverhill, MA on Merrimack st. . I am not sure if they made them or purchased them from Boston or NY but they were small, maybe 4" tops and were a Golden had egg wash top and had both beef and potato inside each one. They were moist and flaky. Most I see are very big and don't combine both beef and potato. I know there has to be some place that would ship around NY or MA.. My family has not been the same on Christmas without them. We tried making them but it just was not as good as ones I you can get from a good Jewish Deli.. Help please I am now living in TN and no delis in close proximity. Thanks!!
