It’s liquid just like chicken broth but used mainly for cooking, it’s stronger and made from boiling the bones and cartilage instead of just the meat.

stock is the word for liquid made from the bones of whatever type animal you might have used to make a soup when you take the bones and make a liquid from it that is called stock. it is usually much thicker than just plain water. i hope you do try this dish you can buy chicken or beef stock at any grocery store
