I put vinegar at the end of soy sauce, water, sugar, and boiled it. Add vinegar at the end when it starts to boil. The ratio is soy sauce (1) water (1) sugar (0.5) vinegar (0.5)
STEP 4/4
If you put lotus root in a hot sterilized glass bottle and boil soy sauce, the soy sauce pickle is completed. If you want to leave it for a long time, boil it three days later, cool it down, and add soy sauce to it, so you can leave it for a long time.
