In Midwood, Brooklyn, there’s a luxury kosher grocery store called Pomegranate serving the modern Orthodox and Hasidic communities. It looks like a really nice Whole Foods. There’s a wide selection of kosher cheeses from Italy and France, wasabi herring, gluten-free ritual foods and nicely toned wood flooring.

The snack section is impressive. There’s a long aisle bursting with little bags of chips and pretzels, suitable for putting into school lunch boxes. That’s important because Orthodox Jews spend a lot of time packing school lunches.

Nationwide, only 21 percent of non-Orthodox Jews between the ages of 18 and 29 are married. But an astounding 71 percent of Orthodox Jews are married at that age. And they are having four and five kids per couple. In the New York City area, for example, the Orthodox make up 32 percent of Jews over all. But the Orthodox make up 61 percent of Jewish children. Because the Orthodox are so fertile, in a few years, they will be the dominant group in New York Jewry.

Another really impressive thing about the store is not found in one section but is pervasive throughout. That’s the specialty products designed around this or that aspect of Jewish law. There are the dairy-free cheese puffs in case you want to have some cheese puffs with a meat dish. There are the precut disposable tablecloths so you don’t have to use scissors on the Sabbath. There are the specially designed sponges, which don’t retain water, so you don’t have to do the work of squeezing out water on Shabbat.
