Is wheatlet the same with semolina?
While similar if not exactly the same, semolina tends to be finer, but Cream of Wheat or Wheatlets can be used the dumpling will be a bit coarser and thicker, I would soak it in warm water to make the dumpling, I used to go to a Hungarian restaurant in Toronto Canada, I am a former chef and they used to make one for a soup, and I have used them soaked or the fine semolina in my German spatzeli dough.
