The elusive purple-fleshed sweet potato Murasaki Imo
After the red velvet, kuromame (black sesame), matcha and kinako, my one other love is sweet potato! Particularly, the elusive and rather expensive purple-fleshed variety. Many regard the sweet potato as a wholesome and vitamin-stuffed carbohydrate, a lovely alternative to the regular spud in bangers and mash or a flexible ingredient used in both savoury and sweet dishes or snacks. For us, me & my family & Singaporeans in particular, sweet potatoes are a very humbling edible root. And they are symbolic of the Japanese Occupation during WWII.
Sweet potatoes were (and for some, still are) a common root vegetable grown in back gardens, etc. A hardy root, sweet potatoes can grow in many types of soil and rarely need pesticides. It is commonly known to us as belonging to that category known as ‘poor man’s food’. But like all poor man’s food, they are not only cheap and easy to grow and cook but delicious as well. They lose very little of its beneficial elements after cooking too. Both the root and its leaves can be eaten. Sweet potato leaves fried in belachan is a common Malaysian, Singaporean nyona dish that’s fragrant and quite gorgeous.
During the Japanese Occupation when rice was scarce and rationing was implemented so as to feed starving families, people were encouraged or forced to use whatever land they had to grow tapiocas, yams and sweet potatoes. However, sweet potatoes were the most commonly grown and the one root that is to today still almost immediately associated with WWII. As my gramma says, it was a sweet potato for breakfast lunch and dinner every day of the week and sometimes there wasn’t even enough to go round. There were even some people whose legs swelled up and became too painful to walk from such an imbalanced diet and malnutrition. Today, although sweet potatoes form the basis of many delicious treats, desserts and savoury dishes, when cooked in the most simple way – washed and scrubbed, then steamed and broken into 2 to share amongst family members – they are symbolic of the pain and suffering our ancestors (living or dead) had to go through during the Japanese Occupation.
On a lighter note, a favourite Chinese dessert of mine is the sweet potato ginger sweet soup. My maternal gramma once cooked it for me after a day at kindergarten but instead of using the local orange-fleshed sweet potato which can be found at all markets and bought for cheap, she’d used a purple-fleshed sweet potato that on cooking had dyed the soup a light pinkish purple. As I remember it today, it was a REAL treat! How different that soup was and although it didn’t exactly taste vastly different, its vibrant colour certainly gave it a special twinkle. Somehow, as the years have passed and I’ve grown up, finding these purple-fleshed potatoes are like searching for a needle in a haystack. My father, who used to have a little farm patch of his own and had started growing vegetables and sweet potatoes as a young boy of 12, reminisced of his days of attempting to grow the perfect purple potatoes.
Unfortunately, these purple potatoes are ridiculously hard to find here in Singapore. Instead, Australian orange-fleshed ones and the yellow-fleshed purple skin Japanese sweet spuds are increasingly popular in local markets. The purple-fleshed spud is nowhere in sight, not even a trace! Nevertheless, these purple spuds which are known as murasaki imo in Japanese are also hard to find even in Japan, being only available at certain times of the year in select supermarkets. Over the weekend, we were lucky to stumble upon these at Isetan which bring these in only once a year. They timed it well I suppose, since it coincided with their Okinawan food fair.
You can imagine my happiness…to have found my purple Queen once again.

And with these treats we took home, I proudly declared it tea time!
Now, to fully and very completely satisfy my purple imo cravings, I need to go find me this! Pocky…oh, it shall take me back to my childhood and high school days – chomping down on stick after stick during a boring lecture. Bliss. Next on my agenda: find a way to plant these beautiful spuds in my own garden. With our ridiculously hot weather, fertile soil and green-fingered parents, we might be able to successfully harvest my purple Queens.
