There's plenty of kvetching over knishes in New York and beyond.

A fire at a Long Island factory billed as the world's biggest maker of knishes has led to a nationwide shortage of the fried, square doughy pillows of pureed potatoes and other fillings.

Gabila's original Coney Island square knishes have been off the market for at least six weeks.

One of the co-owners of the company founded in 1921 says she's been getting calls from customers around the country asking about them.

Gabila's sells the knishes online and at retail outlets around the country, but the New York metropolitan area, Florida and California have the highest sales.

The good news, the co-owner says, is that the machinery should be fixed by Thanksgiving, which coincides with the start of Hanukkah.
