How to Make 'Beni-imo Purple Sweet Potato Paste'

Beni-imo Purple Sweet Potato Paste

Beni-imo is the word for purple sweet potato in Okinawa. If you have been in Okinawa for a bit, you'll know about these little tarts shown below. 'Beni-imo taruto', or beni-imo tarts, are the most well-known Okinawan souvenir. Imo (pronounced ee-moh [e as in eat]), or potato, was a large part of the Okinawan diet for centuries. Rice is difficult to grow in this subtropical environment and people depended on potato varieties as the staple in their diet. Now I am not saying beni-imo is the key to longevity, but Okinawans are some of the longest living people in the world...Anyways! This recipe shows you how to make the paste which you can squeeze on top of little tart crusts, large pie crusts, cookies, cakes, and other desserts.
