Peel and grate the carrots using the large holes of a box grater or food processor with a grating attachment. Place in a large mixing bowl.
Add the golden raisins to the grated carrots and toss gently to combine.
In a small bowl, whisk together the olive oil, honey, and lemon juice until well combined.
Season the dressing with salt and freshly ground black pepper to taste.
Pour the dressing over the carrot and raisin mixture and toss until everything is evenly coated.
Cover and refrigerate for at least 15 minutes to allow flavors to meld.
Just before serving, fold in optional ingredients like toasted walnuts and fresh parsley if using.
Give the salad a final toss, taste, and adjust seasoning if needed before serving.
