I make this for rosa all the time. Super easy, Wuhan classic that my mom and I enjoy. Buy lotus root, peel, cut into 2-4 chunks, wash.

Simultaneously, start with cold water, put in spare pork ribs. bring to boil. drain and get rid of impurities.

chuck everything into the instant pot.

the lotus root has salt.

enjoy soup

Alternatively, radish soup is similar process but with daikon radish.
