Place the couscous in a serving bowl. Add 1 1/2 cups boiling water and stir. Cover tightly and let stand for 10 minutes. Meanwhile, heat the jam in a small saucepan over medium heat or in a microwave on low until bubbling, 30 to 60 seconds. Remove from heat. Immediately add the vinegar, then the oil, and mix until combined. Season with the salt and pepper; set aside. Fluff the couscous with a fork and stir in the scallions and almonds. Add the vinaigrette and toss. Serve warm. Tip: This slightly sweet side dish is an ideal accompaniment to grilled or roasted pork or chicken. You can also drizzle the vinaigrette over rice or quinoa instead of couscous.
