FAQ Section
- Can I use instant mashed potatoes?

It’s best to serve them fresh, but you can prepare the dough in advance and refrigerate it until ready to fry. - Can I freeze the potato mochi?
Yes, freeze the uncooked mochi balls on a tray, then transfer to a zip-top bag. Fry from frozen when ready to serve. - What oil is best for frying?
Use a neutral oil like vegetable or canola oil for frying, as they have a high smoke point and won’t overpower the flavor of the mochi. - Can I bake these instead of frying?
Yes, you can bake them at 375°F (190°C) for 20-25 minutes, turning halfway through, but they won’t have the same crispy texture. - How can I make the mochi softer?
If you want a softer texture, add a bit more mashed potato or less rice flour. - What can I use instead of soy sauce?
Tamari or coconut aminos are great gluten-free alternatives to soy sauce. - How do I store leftover mochi?
Store leftover mochi in an airtight container for up to 2 days. Reheat by frying or microwaving. - Can I use a different type of flour?

Pair with miso soup, pickled vegetables, or a fresh salad for a balanced meal.
Conclusion
Potato Mochi is a savory twist on the traditional Japanese sweet mochi. Instead of the usual sweet fillings, this version uses mashed potatoes mixed with glutinous rice flour to create a chewy, comforting snack. The dough is slightly savory, and you can stuff it with a variety of fillings, like cheese, vegetables, or even a dash of soy sauce for extra flavor. Once pan-fried or baked, the outer layer becomes crispy, while the inside stays soft and chewy, offering a delightful contrast in textures.
This dish is a great snack or appetizer, and it’s incredibly versatile—add in your favorite spices or herbs, or dip it in a sauce like soy sauce or teriyaki for added depth.
