Private equity firms have plenty to worry about when buying companies, including improving revenue and keeping costs in check.

But what about keeping kosher?

Yaakov Y. Horowitz, the chief rabbi of the Manischewitz Company, the matzo maker, is responsible for ensuring that the company stays true to its Jewish principles under its new private equity owner, Sankaty Advisors, an arm of the private equity giant Bain Capital, which bought the company a year ago.

“Sankaty is not coming from someplace that is familiar with the sensitivities,” Rabbi Horowitz said Wednesday evening at a Manischewitz event in Manhattan. “There’s a very important educational role that I play.”

The 58-year-old rabbi heaped praise on the executives from Sankaty, saying they have “shown a concern for kosher in a special way,” a trait that is “not something private equity firms are famous for.”
