Mix together all of your ingredients in a pot and warm it on the stove. Bring that to a boil over a medium heat. You don’t need it to boil for long or to boil rapidly. Just make sure that the sugar and salt has dissolved all the way.
Once they have dissolved, you can take them off the stove and let the mixture cool. It can be put into the fridge to cool faster, and once your brine has cooled completely, then it is ready to be used.
