Without using the inner cover (ceramic steaming partition), put the food (or medicinal materials) directly into the ceramic liner, add a proper amount of water (it is appropriate to just submerge the food or a little more), and then cover the ceramic upper cover.
Step 2 isolate cooking
Put inedible medicinal materials in a ceramic liner, put them in a ceramic isolation cover, put food on a ceramic isolation cover, and stew with water.
Step 3 stew in raw juice
First put the ceramic steamer into the ceramic liner, then put the food on the ceramic isolation cover, and directly cover the ceramic upper cover without adding water. You will get a small bowl of food juice after this stew.
