Sweet Potato Manju, an English shortbread wrapped around Japanese sweet potato.

Here is a video showing how to make them.

The Filling

  • 500 grams uncooked sweet potato
  • 100 grams sugar
  1. Boil the potatoes until soft, about 20 minutes, then sieve.
  2. Put that in a saucepan with the sugar and cook to melt the sugar and remove water from the potatoes.
  3. Cook until the mixture doesn’t stick to the pan. About 10 minutes.

The Outer Shell/Cookie

  • 40 grams butter
  • 65 grams sugar
  • 35 grams whole egg
  • 120 grams flour
  • 2 grams baking powder
  1. Cream the butter and sugar, add the egg and mix until smooth.
  2. Add the flour and baking power and stir until incorporated.
  3. Chill (to firm the butter) for 30 minutes then roll out.
  4. Take dollops of the jam and enclose it with the rolled cookie dough.
  5. Bake for 50 minutes at 350F/180C.

Very appealing.
