In each of two 3-quart saucepans bring half of water, oil, cinnamon, cumin, salt, and apricots to a boil. Stir 1 box couscous into each pan and let stand, covered, off heat 5 minutes. Fluff couscous with a fork and transfer to 2 shallow baking pans to cool as quickly as possible. Cool couscous completely and with your fingers break up any large lumps. Couscous may be made 1 day ahead and chilled, covered. Bring couscous to room temperature before proceeding.
Fluff couscous with fork again and stir in currants, pistachios, mint, and salt and pepper to taste.
