When you take these carrots out of the fridge, you’ll notice the vinaigrette dressing has congealed. Don’t reheat the leftovers, though, because it will soften the carrots too much, and the salad will lose its refreshing taste.   Just take the carrot salad out of the fridge about 30 minutes before serving it. Then toss it with two spoons, and it'll be perfect.   If you haven’t planned ahead and really want to eat some right away, you can use the microwave for a few seconds just to take the chill off.
