Calorie count is for full recipe.
- 300 g sweet potato
- 8 kanro-ni chestnuts (sweet-simmered chestnuts)Note
- 1/2 tsp powdered kanten agar
- 80 g sugar
- 1/6 tsp salt
- 150 ml water
Cut the sweet potato into rounds 2 cm thick. Peel off the skin and a thin layer beneath it, and place in water. Transfer the sweet potato slices to a pot and add enough water to cover, then heat over low heat and cook for about 20 min.
Use a paper towel to wipe the excess syrup off of the chestnuts. Line your mold with plastic wrap.
When the sweet potato has softened, strain and either place in a food processor and process for about 20 sec, or press through a strainer. Mix in the sugar and salt while the sweet potato paste is still hot.
In a pot, combine the powdered kanten agar and water, and heat over low heat. When it comes to a boil, stir for about 1-2 min to dissolve. Add the sweet potato paste and stir with a wooden spatula, scraping the bottom of the pot so that nothing sticks, for 2–3 min while it cooks down. Let cool until safe to handle and pour into a mold. Smooth out the top surface and press the chestnuts into it, and let cool to set.
You can use a bento box or other food storage container you have as a mold. Kanten will set naturally at room temperature, so there's no need to put it into the refrigerator.
To store, cover the surface with plastic wrap and store in the refrigerator.
