3. Secret Ingredient: Fish Sauce
One ingredient that you likely have not even thought about putting in your burgers is the fish sauce. However, you should definitely consider adding this to your mix if you are looking for a perfect cheeseburger to serve your guest. The fish sauce helps to provide depth and complexity to the meat. You should add about 1 ½ tbsp per pound of meat. This will provide the depth of flavor that you want, without making people think that they can taste it.
Many recipes in the past for meatloaf had you add in some Worcestershire sauce. This was basically the fish sauce from the mid-20th century in America. Fish sauce provides more complexity to every dish that it is added to. While there is some sodium in the fish sauce, the sauce actually will provide a higher amount of moisture than it will take away. This secret ingredient takes your typical cheeseburger from good to great.
