STEP 2/3
Place the stock in a saucepan before kneading.I always add the three musketeers of dipori, anchovies, and kelp.
Put the ground purple sweet potatoes into the flour and knead them little by little by little by little by little.
As I kneaded it, it didn't feel sticky and tough, so I added potato starch. Cover the dough with plastic and leave it at room temperature for 30 minutes to make it much more chewy
