For the dressing, in a large bowl whisk together the mayonnaise, lemon peel, lemon juice, sugar, salt, and pepper.
Using a vegetable peeler, shave carrots into ribbons. Toss carrots with dressing, raisins, and sliced green onions. Season with salt to taste. Let salad stand about 10 minutes until carrots are slightly wilted, before serving. Toss frequently when serving to distribute dressing. Salad can be covered and chilled up to 4 hours before serving. Toss well before serving.
