- 3 Tbsp Potato Starch
- pinch Salt
- 1 Tbsp Vegetable Oil
Mitarashi Sauce (optional)
- 2 Tbsp Sugar
- 1 Tbsp Soy Sauce
- 1 tsp Potato Starch

Instructions
- Steam the Potatoes: Peel the potatoes, cut them in half, and steam them in a saucepan for about 10 minutes, or until they're soft and easy to mash.
- Make the Dough: Transfer the steamed potatoes to a large bowl and mash them until smooth. Add potato starch and a pinch of salt, then mix well until a soft dough forms.
- Shape the Mochi: Take a portion of the dough, roll it into a ball, and gently flatten it with your palm to form a round, mochi-like shape. Repeat with the rest.

- Substitute: You can substitute potato starch with corn starch, tapioca starch, or glutinous rice flour.

- If your potatoes have excess oil after pan-frying, you can use a paper towel to remove them.
- Potato mochi can be enjoyed in various ways; see the “How to eat” section for more details.
What is the ratio of tapioca starch to pounds of potatoes? I cannot find a measurement.
Hi Patty, thanks for your question! You can use tapioca starch the same quantity of potato starch in the recipe card. The texture of the tapioca version might be less chewy, but it will still be delicious! I hope this is helpful!
Great alternative when you don’t have rice mochi. So easy. I’m going to try adding different sweet and savory fillings. Thx for sharing!
Yes! I’m happy to hear you like the recipe! Thank you for your comment, Linda!
