Turkey Stock: Made by simmering turkey bones, sometimes with a bit of meat still on them, along with vegetables and herbs for a long time. It’s typically richer and has a more concentrated flavor because it extracts gelatin from the bones, giving it a thicker texture and deeper flavor.
Turkey Broth: Made from simmering turkey meat (sometimes with bones) and vegetables for a shorter time. It tends to be lighter in flavor and more liquidy compared to stock.
In recipes, you can often substitute one for the other, but keep in mind that if a recipe calls for stock and you use broth, you might get a lighter flavor and a less rich texture. Conversely, if you use stock in place of broth, you might get a more intense flavor and thicker consistency. Adjusting the seasoning might be necessary based on what you're using.
