This dip will impress your holiday guests but only you'll know how easy it is. Make it ahead to save some stress on party day plus it gives the dip flavors to really mellow. It features our lactose-free sour cream, but for those who don't have a lactose intolerance, it can be made with traditional sour cream as well It’s sure to be hit with everyone, including those who are lactose intolerant. Don't substitute Cooking Sherry for the Dry Sherry - the flavor is decidedly different and Cooking Sherry is loaded with salt and doesn’t add the right sweet, nutty flavor.
