Purple Sweet Potato Pie

You know, I'm beginning to think I'm a born klutz. I sprained my ankle on Monday. YES, AGAIN. I last sprained it a couple months back. So it is seriously not funny at all.

Purple Sweet Potato Pie


Either I have weak ankles, or I am just too clumsy/careless for my own good. It is such a pain (literally, and figuratively for the wallet) to be injured. I went for a traditional massage, and also, acupuncture (at the TCM person's recommendation). I mean, I thought it wouldn't hurt (such a pun) to try acupuncture since I have a history with sprained ankles.

Oh my god. Have you guys ever tried acupuncture? It sure hurts like crazy. I mean, when the guy pierced the needles in, it was prickly, and what hurt the most was when he twisted the needles. *insert shouts of pain here* After the treatment, my leg felt so heavy and numb, and I was shuffling my feet rather than walking. However, my ankle felt so much better today. Like seriously. So at least the pain was not for naught.

So yes, sad story of my life. Tsk.


And yes, moving on to the food part of the post...

Purple sweet potatoes! I swear I spam sweet potato goodies at least once a year when my best friend gifts me with them. Following the sweet potato buns here, I have this sweet potato pie.


I had some purple sweet potato powder that I got which I used in the tart dough. The taste was pretty negligible so you can omit and replace with flour if you do not have sweet potato powder on hand. I couldn't decide on a recipe for the sweet potato pie filling, so I just sort of made up my own.


The results were quite decent (I think). It turned out quite creamy (albeit a little too sweet), and the colour was a really gorgeous shade of purple (aided by some extremely purple sweet potatoes). If you scrutinise the photos really carefully, you will see that the filling appears to be a little brownish in some shots, this was caused by the melting caramelised hazelnuts. So if you don't decorate the pie like I did, the filling will stay nice and purple.


Happy December folks!
