Bring the apples, orange juice, apple cider vinegar to a boil in a dutch oven or heavy bottomed pot. Reduce heat to medium-low, cover and simmer for 20-30 minutes or until the apple slices are disintegrating, stirring occasionally.
Press the apple mixture though a food mill in batches untill pureed. A food processor, blender or even a potato masher can be used.
Pour the puree back into the dutch oven, add the sugar, cinnamon, allspice, vanilla, and salt stirring until the sugar and spices have dissolved.
Cover and cook over low heat, stirring every 5-10 minutes for 1 1/2 - 2 hours or until mixture has thickened and holds its shape in a spoon. Remove from heat. Pour into jars and store in the refrigerator for 3-4 weeks.
