You may have salt and sugar in your kitchen already. Consider purchasing the rest of the ingredients from your local grocery store. Wash and rinse a large sized bowl thoroughly so you can start preparing the Big Mac sauce at home. It is absolutely crucial to ensure the container or bowl is clean to remove any harmful bacteria and germs.
Peel white onions and clean them thoroughly using fresh water. If you have a mince machine, you can simple process the onions in it to create minced white onions. Unpack the French dressing and take out at least ½ cup of Mayonnaise. Combine and mix all the ingredients in the bowl until the required texture is achieved.
You will be required to allow the ingredients to soak into each other. This can be done by placing the bowl of sauce in a refrigerator overnight, for at least five to six hours.
Take out the sauce from your refrigerator and stir it before using. Apply it on the bun and enjoy your fresh home-made Big Mac burger.
