3/4 cup kosher salt
In a large, heavy saucepan, combine the apple juice and vinegar and whisk over medium heat. Whisking continuously, pour in the sugar and salt. Continue whisking until the seasonings are completely dissolved, but do not allow the mixture to come to a boil. Remove the pan from the heat and cool completely. If reserving for a later use, use a funnel and pour the marinade into a large bottle or container. You can store this marinade in a tightly covered container in the refrigerator for up to one year.
