Cut 1 quarter from one of the apples.Wrap the unpeeled quarter in plastic wrap and reserve. Peel, core, and quarter the rest of the apples. Chop the peeled apples into ½-inch pieces and toss with the lemon juice in a medium bowl.

Heat the olive oil in a heavy-duty 4-quart saucepan over medium-low heat. Add the leeks, onion and shallow; cook, covered, stirring occasionally with a wooden spoon, until just tender, 6 to 8 minutes.

Stir in the ginger, tomato paste, garlic, and curry powder and cook, stirring, until fragrant, about 1 minute. Add the wine and cook, uncovered, stirring occasionally, until the liquid has almost evaporated, 2 to 3 minutes.

Add the chopped apple, parsnips, and potatoes and stir to coat well. Add the chicken broth and 1-½ tsp. salt and bring to a boil over medium-high heat, stirring occasionally. Reduce the heat to medium low, partially cover then simmer, stirring occasionally, until the apples and vegetables are very tender, about 30 minutes.

In a blender, purée the soup in batches until completely smooth. Transfer the soup to a clean 4-quart saucepan, stir in the coconut milk, and season to taste with sea salt and fresh ground pepper. Bring the soup to a simmer over medium heat, stirring often. Cut the reserved apple quarter into small dice. Serve the soup sprinkled with the diced apple and chives.
