Korean Sweet Potato Pie: Holiday Recipe # 9

Just to quickly clarify before you read, this is not a Korean pie...this is a sweet potato pie made with Korean/Japanese sweet potatoes.

After living in Hong Kong with its many western conveniences (I could easily buy non Asian goods with no problem) moving to Seoul, Korea was hard for me. I was used to being able to easily shop for whatever ingredients I needed and cooked whatever I liked with no problem.

In Seoul, I found myself improving my Korean cooking, simply because there was so much Korean food available; it just made sense to cook Korean. Not only was it more convenient, it was much more economical. With my grandmother by my side, I learned so much of the traditional foods of my country and it was wonderful.

Until Thanksgiving rolled around. In Hong Kong, I was able to run to one of a number of supermarkets and get almost every single item I needed to host a full-fledged Thanksgiving meal. The turkey was delivered to me defrosted and I managed to feed 30 people out of the world's tiniest refrigerator. Turkey, ham, stuffing - several pies - the full works came out of that tiny kitchen and fridge. Seoul was not as convenient -there were some western food import shops that would have a lot of what I needed, but they were pricey. Costco was where I ended up buying the turkey (a British turkey with an accent) and I also got my ham there. I had to figure out dessert however.

Husband flew to HK for business so I sent him to a store for pumpkin and he brought back 8 precious cans for me. But I decided that I needed more than pumpkin pie for our meal extravaganza (invite list of 30 people) so I decided to try making something I'd never made - sweet potato pie. I made it with a Korean twist, using Korean sweet potatoes (고구마). The evening of the party it drew better reviews than the regular pumpkin pie.

Since coming back to the US, I haven't had the urge to make sweet potato pie, but for my church small group I decided to try it again - to see if it still tasted good and to see if it would be a favorite. With a topping of homemade sweetened whipped cream...well let's just say there are no leftovers.

This pie in particular really appeals to the Korean palate, as I think it has a restrained sweetness that comes through, but isn't overwhelming. Koreans are also incredibly loyal to their sweet potatoes and the flavor of them simply can't be beat. The texture is different from traditional sweet potato pie as it has a firmness and structure that normal sweet potatoes cannot bring.

As a note, I do make my own homemade pie crust, but feel free to use one of those premade pie crusts. It will save you a few steps. Those of you interested in making your own crust, I've included a recipe. I used to make pie crusts by hand using only a pastry cutter and a bit of elbow grease. Those of you not inclined to washing a huge food processor or do not own one, definitely invest in a pastry cutter.

Korean Sweet Potato Pie
1 9 inch pie crust, prepared

2.5 lbs of Korean/Japanese sweet potatoes
1 cup of brown sugar
1 cup of heavy cream
3 eggs
1 tablespoon vanilla extract
1 tablespoon freshly grated ginger (or substitute 1 teaspoon ground ginger spice)
1 1/2 teaspoons ground cinnamon

1 beaten egg white, for brushing onto pie crust.

Preheat oven to 400. With a fork, puncture your sweet potatoes with a few pricks. Place potatoes on a baking sheet and bake until potatoes are squishy, anywhere between 45 minutes to an hour. Allow to cool. (I usually do these first thing in the morning and set them aside.)

Preheat oven to 400. When sweet potatoes are nice and cool, scoop out potato flesh. Take 2 cups of sweet potatoes and put them in a bowl. Mash them up with a potato masher OR process them with a hand blender. Get the texture to be fairly smooth and uniform.

Add cream and brown sugar. Mix until well blended. Add eggs, vanilla, ginger and cinnamon. Mix well.

Brush pie crust with beaten egg white. Pour sweet potato filling into crust. Bake at 400 for 45 minutes, or until filling is set.
Serve with whipped cream.

I would love to try your sweet potato pie. Need to buy some shortening though, otherwise hard to get a flaky crust. I made pumpkin pie last week but do not like the taste so much.

Thank you for baking the sweet potatoes! So many recipes just call for boiling or the canned variety, but to me I think baking them really bring out the natural sweetness.

I found this on tastespotting; thanks for posting!! As an American married to a Korean and going on a Thanksgiving retreat with a Korean student association I appreciate that I'll be able to make a pie I'm sure they'll love! ;)

My mom loves sweet potato pie. I think I may have to make this one for her! Thanks and lovely photos.

Jane said...

Just put my Korean sweet potato pie in the oven. I hope it tastes as good as it looks because it looks amazing! I'm also using your pear, arugula and prosciutto recipe. This coming from a woman who can't remember the last time she even made scrambled eggs! Thanks, Joanne.

Sweet potato is a highly nutritious and an alternative for food for their valuable contents of carbohydrate, protein and carotene, which are necessary for normal development and even for the sexual development too, believe it or not. Sweet potato is really helpful for welfare and our body.

I'm excited to try this out for Thanksgiving dinner, as I know my mom will appreciate it. Is there anything I can substitute for heavy cream? She's not supposed to have dairy at the moment...

Jieun ... you could try coconut milk - the kind in the can - super rich, and trying to sort of skim off the super fat solids at the top and get a cup of that. It will change the flavor a bit but not to the point of detriment. I also think it might be really yummy with almond milk, which is next to the soy and rice milks at your local grocer. Good luck and let me know what you end up substituting and how it comes out!

Apparently the pie dish that my co-worker and I own can only be used in max 375 degree oven. The recipe calls for 400 degrees. Can I bake the pie at 375 instead and for how long?

Diana said...

I'm making this for my korean mom this thanksgiving! I think she'll be really surprised!

Connie said...

This is probably a big no-no in baking, but is there a pre-made pie crust/pie dough you recommend? or any of your readers recommend?

Joanne Choi said...

Sure - I remember posting on a few pie crusts that were ready made that were considered good. I think any good one made with BUTTER (I think Whole foods had some) would yield the best results, but dont' stress TOO much about it.
