Reworking a Family Favorite

Every Thanksgiving my extended family gets together for our annual celebration, and it is basically a feeding frenzy. Before the main course of turkey (and stuffing and cranberries and mashed potatoes), it is traditional to have a gigantic spread of appetizers, mostly chips and dip and crudite and salami and cheese type of stuff, so that we are all usually stuffed by dinner time. My favorite appetizer growing up was always the french onion dip, made with a base of sour cream and mayonnaise, and if I dared read the ingredient label and the powdered flavoring packet, lots of chemicals and flavoring agents. This sweet coriander-onion dip is my “healthified” version of that dip, reworked to not include any flavor packages or other junk. Here it is served with a sweet potato fries recipe, but can certainly be used for anything dippable!

Sweet Potatoes vs. Yams

Just some trivia for you–the yam and sweet potato come from two different plant species. True yams are from a botanical plant that most likely originated in Africa. Sweet potatoes are a New World plant, “discovered” by Columbus. Sweet potatoes are generally harvested and in peak season in the U.S. from October-December. Sweet potatoes store well though, so are often available year round. Yams usually are a deeper orange color than sweet potatoes. True yams are drier and starchier than sweet potatoes. Both are an excellent source of Vitamin A and potassium. However, what we call a “yam” in the U.S. is usually a variety of sweet potato, as true yams are not common here. Plan to use sweet potatoes within a week, and keep in a cool dark place. Substitute them for potatoes in mashed potato recipes, adding sugar or maple syrup to sweeten, and spices such as cinnamon or nutmeg.
