A matzoh ball is a dumpling made of crushed matzoh (matzoh meal). They can be made firm and heavy, with a slightly chewy texture, or very soft, with a melt-in-your-mouth lightness. My matzoh balls are fairly traditional, combining matzoh meal with some type of fat (preferably chicken fat) for richness and flavor, seltzer, and eggs to bind all the ingredients into a loose batter that thickens when chilled and produces light, fluffy balls that retain their shape when boiled. The onion and parsley in mine are not traditional, but I like mine that way. I prefer my soup very simple--just wonderfully rich homemade stock along with perfectly cooked soft matzoh balls that dissolve in your mouth. Truly...a soup for the soul...

Refrigerating the batter for several hours is the critical window that dictates the final density of each dumpling; skipping this step leaves the matzoh meal unable to fully hydrate, resulting in a dense core instead of a tender structure. Fat molecules from the schmaltz coat the starch granules, while carbonated water introduces microscopic gas pockets that expand under thermal energy. Jumbo eggs supply both lecithin for emulsification and albumin to trap those expanding gases during the simmer. Working with chilled batter requires wet palms to prevent sticking, and shaping must remain gentle to preserve the interior aeration.
Simmering these dumplings in plain salted water rather than the final broth keeps the cooking liquor clear and prevents the starches from muddying the flavor of the chicken stock. Boiling them for 30 to 40 minutes guarantees complete gelatinization of the meal, with floatation and a bloated visual appearance signaling absolute doneness. Transferring the finished spheres directly into warm broth after a brief resting period allows the exterior to absorb savory saline notes without dissolving.
Leftover dumplings stored in their broth for up to 24 hours undergo a continuous hydration process, absorbing additional liquid and softening further in texture. Reheating requires maintaining a gentle simmer to prevent the exterior membrane from rupturing under aggressive agitation. Broth clarity can diminish during extended storage due to escaped starches, making a quick strain advisable if presentation matters.
Freezing uncooked matzoh ball batter is not recommended because carbonation dissipates entirely over sub-zero storage periods, destroying the lift achieved by seltzer. Cooked spheres, however, hold up well when frozen submerged in stock for up to one month, provided they are thawed slowly in the refrigerator before reheating on the stovetop.
