Vanilla Mashed Sweet Potatoes

Well, here we are – as of this writing, it’s 6:40 a.m. the day before Thanksgiving and we’re brining our heritage, pastured turkey.  As we pulled the bag of giblets out of the cavity, both Beloved and I marveled at the size of this bird’s innards; they are huge compared to an industrially produced turkey.  I purchased some tapioca flour in anticipation of making giblet gravy (for Beloved, Thanksgiving isn’t Thanksgiving without giblet gravy, and I’ve decided I’m not thrilled with arrowroot for things like gravies), and I do believe there is going to be more giblets than gravy.  Oh, darn. </sarcasm>.

Anyhoo…on to the recipe, as promised.  You can thank me in the comments section. 😛

While we were making our weekly excursion through our favorite natural foods store in Akron this last weekend, I was delighted to see a display of Japanese sweet potatoes.  We’ve only ever eaten them once, and I’d never cooked them before at all.  They weren’t cheap – they cost twice what the garnet “yams” that were on sale did – but I grabbed three huge ones and put them in our basket, meaning to save them all for Thanksgiving.

I didn’t, of course, but I’m so glad I decided to cook one ahead of time.  Because this dish?  Is stupendously good.

Japanese sweet potatoes, or Satsumaimo, are a purple-skinned variety with a creamy, pale yellow flesh.  When prepared this way, they have a texture, and color, similar to Yukon golds.  They are also very, very sweet – much sweeter than the tan or red-skinned, orange flesh sweet potatoes that are so ubiquitous this time of year.  If you’re the type that prefers the “ancient marshmallow yams of sorrow” with their Thanksgiving dinner, a casserole made with Japanese sweet potatoes would need no adornment.

Because they’re so sweet, they are best simply prepared – they would be dynamite roasted, slathered in butter and sprinkled with cinnamon.  Mashed, however, a touch of pure vanilla extract takes them completely over the top – it enhances their sweetness without making them cloyingly so, and gives it a very sophisticated flavor.  (The original recipe I found called for beans scraped from a pod, but wasn’t about to use one of my precious Madagascar vanilla beans on mashed potatoes, I don’t care how good they are.)

If you can’t find Japanese sweet potatoes, use jewel or garnet yams; they have a redder flesh and are a tad sweeter than conventional, yellow-skinned sweet potatoes or Beauregard yams.  You might want to add a touch of honey and grate a little orange zest into them along with the vanilla.  But if you can find the Japanese variety, use them.  You won’t be sorry.

Vanilla Mashed Sweet Potatoes

Vanilla Mashed Sweet Potatoes

serves 6

2 1/2 pounds Japanese sweet potatoes
1/4 cup goat or regular unsalted butter
1/4 cup coconut milk mixed with 1/4 cup water OR 1/2 cup half and half
1 teaspoon pure vanilla extract
salt and freshly ground black pepper, to taste

Bring 2 quarts of water to a boil in a large saucepan.

Peel and cut the sweet potatoes into large cubes and drop them into the boiling water. Cook until tender, about 20 minutes; drain and return to the pan.

Shake the potatoes in the pan over medium heat until the excess moisture evaporates. Reduce the heat to low and add the butter and vanilla to the potatoes; mash lightly with a potato masher. Gradually add the coconut milk or cream, mashing lightly between additions, until the potatoes are smooth and creamy. Season to taste with salt and pepper, and serve immediately.

  1. Drooooooooling here now. And I’m going to do a Google search to see if in my mad dash for the last-minute stuff I forgot for tomorrow might include picking up some of those Japanese sweet potatoes. 🙂

  2. Thank you!!! I am American military living in Japan and we are not allowed to have potatoes or sweet potatoes shipped in from the states… so, we have only Japanese sweet potatoes. I LOVE them, and am always looking forward to more recipes and more ways to prepare them!! Glad you got your hands on some, too!! 🙂

  3. I’ll be making this with regular old garnets because that is what I have in the pantry. Honey and orange zest duly noted. Thank you for not going on about the giblets. Jen totally owns that comment!

  4. I made my own bottle of vanilla extract by putting some vanilla beans in vodka in a really groovy bottle ages ago, but hardly ever touch the stuff since we never cook sweets. This would finally give me a chance to use it.

    Also, and this isn’t the manliest thing I’ve ever said in my life, but if you have a cool bottle (say 250 or 500 ml with a cork stopper) and make some nice vanilla extract it makes a great gift for those hard to shop for friends.

  5. This is a fab recipe. I went searching for a portion of tonight’s dinner and found you. My husband and I love Japanese sweet potatoes (and now this is all we try to buy). The flavors in this are divine! Now to check out the rest of your blog. Thanks again!! Sue
