Egg Drop Soup with Soy and Rice Vinegar
Chicken broth with soft egg ribbons, soy sauce and a lightly thickened base.
The source’s egg drop soup uses one liter of chicken broth, three eggs, soy sauce, potato starch and a little rice vinegar. To avoid starchy clumps, stir the potato starch into a small amount of cold broth first rather than whisking the dry powder into beaten eggs. Add that slurry to the simmering pot until the liquid thickens very lightly. Then swirl the broth and pour in the eggs in a thin stream to make delicate ribbons. Leave them a moment to set before stirring again. The original simply says “two onions” for garnish, which is too much for a small pot; use two spring onions, thinly sliced. Finish with dill or parsley if desired.
