Umukujiandagii – Salty purple sweet potato cake

My cooking school is located in Yomitan and beniimo is a very special vegetable in this village. I did a sweet version of this cake recipe sometime in March this year. It was very popular, and a lot of people loved the color of this cake. If you are not a big fan of sweets then this version is for you. It has no added sugar or additives and makes a great snack for kids.

• 5 oz purple sweet potatoes

• 2-3 branches Chinese chives

• ½ cup of tapioca / sticky rice もち粉 / kuzu flour葛粉

• 1 tsp salt



1. Wash the purple sweet potatoes and then steam them until cooked. The potatoes are cooked when you can easily push a toothpick or bamboo stick into them.

2. Once the purple sweet potatoes have cooled down, mash them in a bowl and add flour, Chinese chives and salt and mix well.

3. If the dough is too dry, add some water to make it smooth. If the dough falls apart it’s too dry, and if it sticks to your hands that means you added too much water.

4. Make the dough into small flat circle shapes, or plump discs. As with the sweet version, the original recipe for umukujiandangi is to deep fry the dough ‘discs’, but as this requires a lot of oil, I cook them in a pan with a bit of vegetable oil. The dough will soak up the oil so add some more oil between batches.
