We have purposely left this recipe simply seasoned with salt and pepper (please make sure to use kosher salt and freshly ground pepper for best flavor), but you absolutely can add some herbs. A sprinkling of fresh or dried thyme is lovely and can be added along with the cream, salt and pepper.   By the way, I do not always provide amounts in the ingredient list for salt and pepper because I often ask you to season to taste. In this recipe I have given you amounts because it is important that the potatoes receive enough seasoning, and this gives you a guide.
