Porridge can be cooked with raw sesame seeds. Raw sesame and cooked sesame have their own nutrition, which can be eaten raw or cooked. Cooked sesame seeds are more fragrant. If you don't grind sesame seeds, you should chew slowly, because if you don't chew the black clothes on the outside of black sesame seeds, your stomach will not digest them, but they will be excreted one by one, and you will not absorb nutrients, so if you don't have the patience to chew slowly, you'd better grind them first and then cook them.
