Purple sweet potato cake

Amongst of all those potatoes out there, this Purple Sweet Potato is..., I believe, the most unique one. Purple sweet potato (we call it "紫いも (Murasaki Imo)" is very popular in Japan, and especially in Okinawa , where the purple sweet potatoes are originated, we can find a lot of purple sweet potato sweets such as ice creams, cakes, tarts and many more.

Not only do these potatoes taste nice and sweet, but also they have a very vivid purple colour, which is perfect when you're making a eye-catching cakes or desserts.

Today I used a packet of purple potato powder that I brought back from Japan to make petite purple potato cake :) As soon as I started mixing in the purple potato powder, the mixture got... well, very very purple ... like a beetroot... and that indescribable homely smell of sweet potato hit my nose.... :) Ahaah, bless me...  Oooh, have a look at the picture! See..., how bright they are!

Unfortunately, I don't know where we can find purple sweet potatoes in the UK although I saw something similar in Whole Foods...  So, please let me know if you see one ;D
