Place the split peas in a bowl and cover with hot water.
Let them soak for 5 hours, then drain completely.
In a small bowl, combine the minced ginger, green chili, cumin seeds, cinnamon stick, cloves, and peppercorns.
Heat the ghee or oil in a heavy 3-quart/liter nonstick saucepan over moderate heat.
Once hot, add the combined seasonings and fry, stirring, until the cumin seeds turn a rich brown and smell fragrant.
Immediately stir in the turmeric, followed by the 7 cups (1680 ml) of water.
Bring the liquid to a rolling boil.
Stir in the drained split peas, apple pieces, and shredded coconut.
Reduce the heat to moderately low, cover the saucepan, and let it gently boil for 1½ hours, or until the split peas are completely soft and have broken down.
Remove the soup from the heat.
Stir in the fresh parsley or coriander and the salt.
Place the lid back on and let the soup stand for 1–2 minutes to allow the final flavors to meld.
Stir once more and serve hot.
In a hurry? You can quick-soak the split peas by covering them with boiling water and letting them sit for just 1 hour.
