This salad utilizes seasonal fruit and greens making it a fabulous salad for winter! Make the pickled grapes a day ahead.
Wash and remove grapes from stems. Slice the stem end off each grape
In a small sauce pan whisk together vinegar, water, and sugar. Bring to a boil.
Place all spices in large mason jar. Add trimmed grapes to jar. Pour hot vinegar over grapes. Allow to cool, then place in fridge. They will be ready to use after 24 hours
Soak kale in a large bowl (or the sink) for ten minutes, swishing the kale around here and there. Use a knife to remove the 'ribs' (the thick, stringy center of each leaf). After drying, stack a few leaves, roll them and thinly slice.
In a metal mixing bowl combine kale, currants, grapes, pickled grapes, apple and a 1/3 cup of the citrus vinaigrette; toss together by hand. Season with salt and pepper and toss again. Add more dressing if needed.
