George Washington Carver, the botanist, educator and inventor, was known as “the peanut man,” but he geeked out over sweet potatoes as much as peanuts. He recorded recipes for sweet potato flour, sweet potato starch and commercial canning. “The delicate flavor of a sweet potato is lost if it is not cooked properly,” he wrote in his 1936 Bulletin No. 38. (His paper booklets were distributed to rural farmers to assist with crop rotation and provide instructions for added-value products.) Dr. Carver considered baking the best way to cook sweet potatoes while preserving the most flavor. Use varieties like Covington, Vardaman or jewel; the sugary notes balance the alliums and warming spices. Raw vegetables or tortilla chips make practical dipping utensils for this spread, or lather the dip over toasted thick-cut bread.

Preparation

  1. Step 1

    Heat the oven to 375 degrees. Using a vegetable brush and water, scrub the sweet potatoes to remove dirt, then place them on a sheet pan.

  2. Step 2

    Bake the sweet potatoes on the top rack until soft to the touch, about 1¼ hours. Let cool for at least 1 hour.

  3. Step 3

    Add grapeseed oil to a large skillet and heat over medium. Add sliced onion, fennel and jalapeño to the skillet and sauté for 15 minutes or until onions are soft and slightly browned. Set aside and let cool room temperature.

  4. Step 4

    Using your hands, gently peel the sweet potatoes and discard the skins. In a large bowl, use a potato masher to mash the potatoes until you see tiny chunks. (The texture shouldn’t be ultrasmooth.)

  5. Step 5

    Using a spoon, stir in the cooked onion mixture along with the ricotta, Parmesan, pecans, lime juice, maple syrup, anchovy oil (if using), salt, onion powder, vanilla and nutmeg. Store the dip in an airtight container, and place in the fridge until ready to eat. (If you have the time, the flavors are always better the next day.)

  6. Step 6

    Just before serving, stir to combine and season the dip to taste with salt. Drizzle it with olive oil, then top it with the reserved fennel fronds and crispy fried onions, if you like. Serve with any combination of bread, tortilla chips or celery sticks.

Wow!!!!!! This is delicious. I made it today as an appetizer for Thanksgiving. Only made a few changes based on my pantry. I used 1 1/2 Vidalia onions (I'm from Georgia) and 2 small fennel bulbs. I caramelized them for a good 30 minutes. I did not use the anchovy oil. I was curious about this recipe because it seem to have all the right ingredients...and was most certainly correct! I can't wait to serve it.

Great on pita chips. Used leftovers as a ravioli stuffing served with a butter/sage/cinnamon sauce. The dip was excellent, but we liked the ravioli even better.

I made this for Thanksgiving, like most, and it was a hit! I didn’t use fennel or jalapeño, but wish I would’ve added the former. I also caramelized the onions. Served this slightly warm with ritz and celery sticks. Best part is that I added flour to the leftovers and made some bomb gnocchi.

I wondered about the name "dip" when i first read this. But I liked the ingredients and flavor profile so I made it for a cocktail gathering. It doesn't work as written! The strands of sliced onions and fennel make this impossible to eat as suggested. After my guests left I lightly pureed the entire batch. The result is more dip-like with the desirable and surprising flavor profile. I think this step should be added to recipe instructions to make the recipe more user friendly.

This is a love-it-or-hate-it dip. The majority of our crowd disliked it but one or two were enthusiastic. Probably won’t make it again. Might work for fritters or as a warm side dish.

I made this for thanksgiving as an appetizer. Definitely make it the day before so flavors meld and come forward. I doubled everything but the sweet potatoes as many suggested and also diced rather than sliced the onion and fennel. The texture seemed weird so I put it in a food processor and blended it together. It was super tasty and a hit. Will definitely make again.
