Your faithful blogger has already directed your attention to a gluten-free Knaidel Mix that can be used for matzoh ball soup. But now the spotlight falls on a different dumpling: a gluten-free German Potato Dumpling Mix spotted at Koglin German Hams, the German food vendor adjacent to Murray's Cheese at the Grand Central Terminal Market.
As you can see from the photo, Werner's Raw Potato Dumplings sport a gluten-free emblem on the upper-left corner of the package front. On a side panel, the words
without gluteninvite you to give this mix a chance.
Many potato dumpling recipes call for egg and/or flour, but in this case the ingredients are "potatoes, potato starch, salt, spices"--so it's safe for many people with food allergies or intolerances. (You can't really taste the spices, in case you're curious about that.) When you add water to the mix, drop the dumplings into boiled water, and wait about 20 minutes, you wind up with buoyant and gummy potato dumplings that are great for soaking up gravy.
Werner's also makes a gluten-free potato pancake (kartoffelpuffer!) mix.
Keep your eyes peeled for the brand wherever German potato products are sold. Online vendors can be found here and here.
