In addition to a small bakery section with loose rolls and bagels, Schwartz's carries these packaged baby bagels in whole wheat and plain.
High gluten flour
High gluten flour helps give bagels their dense chewiness. Schwartz's seems to think most of its clients will be making bagels at home on the regular, as the smallest quantity one can buy is six pounds!
At Schwartz's there's no shortage of kosher cream cheese (to go with the bagels you'll be making with all that high gluten flour...)
For when wine isn't an option, Schwartz's carries all the grape juice you could ever need.
Spicy horseradish is a staple of most Jewish meals. Schwartz's carries regular white horseradish as well as red horseradish, which gets its color from beets.
Sharp, sour pickles
Matzo balls and soup
Schwartz's stocks various brands of matzo ball mix, for a semi-homemade comfort food treat.
They also stock matzo meal, for a truly homemade version.
Sweet and savory kugel, a baked pasta casserole often served at holidays, gets its own special egg noodle.
According to the packaging, Kindl dough (sold frozen) is particularly good for poppy seed or walnut rolls. (Insert obligatory Kindle/reading joke here.)
Kreplach, traditionally served on Purim and on Hoshanah Rabbah, the seventh day of Sukkot, are small squares of rolled pasta dough filled with ground beef or chicken, and folded into triangles. This frozen package aptly suggests using the dough for ravioli, too.
Knishes are a popular Jewish snack often filled with mashed potatoes. Schwartz's carries "Mom's," which with such a name can only be delicious, in potato and...pizza.
