How to Make Potato Mochi: A Step-by-Step Guide

If you're a fan of Japanese cuisine, chances are you have heard of mochi. This chewy and sweet rice cake is popular throughout Japan and has gained popularity around the world in recent years. While traditional mochi is made from glutinous rice, there are many variations that use different types of flour or starch. In this article, we'll be discussing how to make potato mochi – a delicious alternative that's perfect for those who don't eat gluten or prefer a lighter texture.

What is Potato Mochi?

Potato mochi refers to a type of soft and chewy cake made with potatoes as the main ingredient instead of glutinous rice. It's commonly found in Hokkaido, Japan’s northernmost island where potatoes are abundant. The potato starch gives the dough its distinct stretchiness when cooked properly.

Compared to traditional rice-based mochi which can be heavy on your stomach due to their high carbohydrate content, potato-based ones can be more easily digested by your body while still fulfilling your cravings for something sweet and satisfying.


To make potato mochi at home, you will need:

  • 1 pound (454g) Russet potatoes
  • 3/4 cup (96g) glutinous rice flour
  • 1/4 cup (32g) cornstarch
  • 2 tablespoons sugar
  • Pinch salt

For toppings:

  • Kinako powder
  • Brown sugar syrup
  • Grated coconut

Note: You can also add matcha powder into the dough if desired as it adds both flavor and color!


Step One: Cook Potatoes

Firstly peel off the skin from washed russet potatoes before cutting them into small pieces. Put them in boiling water until they become tender enough when pierced with fork tines(about 20 minutes). Remove from heat and let cool.

Step Two: Puree Potatoes

After the potatoes have cooled down, put them in a food processor to puree until smooth.

Step Three: Mix Ingredients

Next, mix all dry ingredients (glutinous rice flour, cornstarch,sugar and salt) in a mixing bowl until well combined. Add your potato puree into the mixing bowl with the dry ingredients and knead together with your hands until you get a smooth dough.

Step Four: Form Mochi Balls

Divide the dough into small pieces around 1 inch of diameter each. Roll them between your palms to form balls before flattening slightly by pressing on top portion gently.

Step Five: Steam Mochi Balls

Arrange mochi balls on parchment paper inside a steamer basket leaving some space between each other for expansion during cooking process.. Put it over boiling water then steam for about 15-20 minutes or until they become soft yet chewy enough when bitten into.

Serving Suggestions

After steaming is done, it's time for toppings! Kinako powder (roasted soybean flour), brown sugar syrup or grated coconut are popular options that go great with potato mochi’s mild sweetness but you can always experiment with different flavors depending on what suits your taste buds best!


Potato mochi is an easy-to-make alternative to traditional glutinous rice-based mochi that offers similar texture and flavor experiences while being both gluten-free as well as vegan-friendly if you use plant-based sugar instead of honey/syrup . With this step-by-step guide hopefully you are now able to make these yummy treats at home without any worries!


What is potato mochi and how is it different from traditional mochi?

Potato mochi, also known as Imo Mochi, is a Japanese rice cake made with sweet potatoes instead of glutinous rice flour. The texture of the potato mochi differs somewhat from traditional glutinous rice flour-based mochi due to the lower gluten content in sweet potatoes and their high water content. While traditional mochi has a sticky and chewy texture, potato-mochi tends to be more firm.

How do I make potato-mochi at home?

Here's what you need:

  • 250g Sweet Potato (peeled)
  • 50g Sugar
  • 100g Shiratamako (Japanese sweet rice flour)


  1. Boil or steam the peeled sweet potatoes until soft.
  2. Mash them into a fine paste using either a food processor or masher.
  3. Add sugar to this mixture while still hot so that it dissolves easily.
  4. Once cooled down for several minutes, add shiratamako little by little while kneading gently until well combined.
  5. Divide into small portions and shape them into balls or any other desired shapes using cornstarch-dusted hands.

Can I use regular wheat-flour instead of shiratamako?

No, unfortunately not! The distinct feature of Imo Mochi lies in its usage of Shiratamako – which is Japanese sweet-rice flour made specifically for making sweets like Daifuku – fluffy white colored confectionery with fillings inside like red bean paste etc.. This specific type of flour has higher levels of amylopectin than ordinary glutinous rice flours which gives the sweetness body & elasticity once cooked properly

Can I store leftover potato-mochi? If yes then how long can they be stored?

You can store these cute bite-sized treats in an air-tight container at room temperature for about 2-3 days. However, it is recommended to consume them fresh as they tend to harden over time and lose their soft and chewy texture. Avoid keeping them in the fridge as they might dry out or become too firm.

How can I enhance the flavor of my potato mochi?

You can add a variety of fillings inside like sweet red bean paste, chocolate chips, strawberries etc.. Also try dusting your potato-mochi with Kinako (toasted soybean flour) which will give it a nutty & earthy aroma along with adding an interesting contrast in taste & texture. Another option is coating your Imo Mochi balls with toasted sesame seeds or coconut flakes after shaping them into balls which not only enhances their looks but also adds crunchiness to every bite!
