1. cut the lotus root into a 2-inch length so it’s easy to work with. Next, cut out a V-shaped notch between two holes and along the length of the root.
  2. Continue cutting between the holes until you’ve cut around the entire outside of the root. The cross section of your lotus root should now resemble a flower.  3. Then, cut the root into ¼-inch slices (0.6 mm).
  3. Once you’ve sliced the lotus root, add the slices to a bowl with vinegared water (1 tsp rice vinegar and 2 cups water). Soak the lotus root slices for 5 minutes to prevent them from changing color and to remove the astringent taste.
