Place the couscous in a serving bowl. Pour 1½ cups hot tap water over the top. Cover and let stand for 5 minutes.
Meanwhile, warm the preserves in a small saucepan over medium heat. Remove from heat and whisk in the oil, vinegar, 1 teaspoon salt, and ¼ teaspoon pepper.
Fluff the couscous with a fork and toss with the scallions, almonds, and vinaigrette.
