Using an apple corer, core each apple and remove ¼-inch from the bottom of the core
Make 6 vertical cuts around the core
Reinsert the ¼-inch core piece to fit into the bottom of each apple
In a small bowl, use a fork to mix together the nut butter and maple syrup
Stir the currants into the nut butter-maple syrup mixture
Add cardamom, cloves, and cinnamon to the mixture
Stuff each apple with a spoonful of this mixture
Arrange the apples in a large skillet (make in two batches if needed)
Pour the apple juice over the apples so it fills the bottom of skillet
Place the apples into their apple juice “bath” in the skillet
Steam covered on medium heat for approximately 35 minutes, or until the apples are soft
Serve hot or cold
