Step 1

Line a small tray with parchment paper.

Step 2

With a small ice cream scoop or spoon, scoop out twelve 2 tablespoon-sized scoops of ice cream (about .75oz /20g) onto the prepared and place in the freezer.

Step 3

In a large microwave-safe bowl combine the sweet rice flour, sugar, and water, cover with plastic wrap and microwave for one minute.

Step 4

Stir the rice flour mixture with a whisk to remove any lumps, re-cover with the plastic wrap, and microwave for another minute.

Step 5

Dip a rubber spatula in water and stir the rice mixture again (do not use the whisk this time - it will be too sticky).

Step 6

Cover the rice mixture one more time and microwave for another 30 seconds. It will now be a sticky dough. If adding in food dye stir it in at this point until it's evenly throughout the dough.

Step 7

Place a large parchment paper on your counter and cover the paper with a generous dusting of cornstarch (or potato starch).

Step 8

With a wet spatula, scrape the dough onto the cornstarch and dust the top of the dough with more cornstarch.

Step 9

Roll the dough into a rectangle no less than 1/4 inch thick (about 12x14inches/30x35cm). Keep dusting the top and bottom of the dough with cornstarch as you roll or it will stick.

Step 10

Once the dough is rolled out, place the parchment paper on a cookie sheet and place in the refrigerator to set for 30 minutes.

Step 11

Once the dough has set, cut circles of dough with a 3 ¾ inch (9½ cm) cutter.

Step 12

Pick up one circle of dough and brush off the excess cornstarch from both sides.

Step 13

Working quickly, take one scoop of ice cream, place in the center of the circle flat side facing you. Press the edges of the dough together around the ice cream ball, squeezing to seal.

Step 14

Wrap the mochi ice cream balls in cling wrap and place seam side down back in the freezer to set. You could use an egg carton to keep them upright. Repeat with remaining circles of dough and ice cream balls. Allow mochi to freeze totally for a minimum of 2 hours in the freezer.

Step 15

When ready to eat, remove from the freezer and let sit for a few minutes to let soften.

Step 16

Store in an airtight container in the freezer for up to 1 week.
