If you are starting with frozen shrimp, be sure to let it thaw before beginning. To thaw shrimp quickly you can place them in a sealed plastic bag and submerge them in a bowl of cold water. Swap the water every 20-30 minutes as needed.
We use a concentrated bouillon base for most of our recipes instead of broth or stock. It’s convenient, takes up a lot less space, has a more intense flavor, and is easily reconstituted with water. You can certainly use broth or stock instead. Just replace the amount of water in the recipe with stock and omit the base.
