Pro Tips

• Toast your black sesame seeds until fragrant before grinding — this step is non-negotiable for maximum flavor depth. You’ll smell a nutty aroma when they’re ready, usually after 3-4 minutes in a dry pan.
• Keep a bowl of water nearby while shaping. Dip your fingers lightly between each mochi to prevent sticking, but don’t oversaturate or they’ll turn gummy.
• Steam over high heat with the lid wrapped in a kitchen towel to catch condensation. Water drips will ruin the texture, creating wet spots instead of that uniform chew.
• Let them cool for exactly 10 minutes before cutting — too soon and they’ll tear, too long and they’ll firm up too much to shape easily.

Ingredients Method

Ingredients

  

• 1 cup sweet rice flour mochiko
• 3 tablespoons black sesame seeds toasted
• 1/4 cup granulated sugar
• 2/3 cup water room temperature
• 1 tablespoon black sesame paste
• 2 tablespoons cornstarch for dusting
• Pinch of salt

Method

 

1. Toast the black sesame seeds in a dry skillet over medium heat for 3-4 minutes, stirring constantly, until fragrant. Let cool, then grind to a coarse powder using a spice grinder or mortar and pestle.
2. In a microwave-safe bowl, whisk together the sweet rice flour, ground black sesame, sugar, and salt until evenly combined.
3. Add the water and black sesame paste to the dry ingredients. Whisk until completely smooth with no lumps remaining. The mixture should look like thick pancake batter.
4. Cover the bowl loosely with plastic wrap, leaving a small vent. Microwave on high for 2 minutes, then stir vigorously with a wet spatula.
5. Microwave for another 1 minute, then stir again. The mochi should look translucent and pull away from the sides of the bowl when done.
6. Dust a clean work surface generously with cornstarch. Turn the hot mochi out onto the surface and dust the top with more cornstarch.
7. Let cool for 10 minutes until just warm to the touch. With lightly wet hands, divide the dough into 12 equal portions and roll each into a smooth ball.
8. Place the mochi balls on a cornstarch-dusted plate and let them sit for 15 minutes to set the exterior before serving.

Frequently Asked Questions

Can I use white sesame instead of black sesame?

Yes, but the flavor will be milder and sweeter. White sesame lacks the earthy depth that makes black sesame special. If substituting, add an extra tablespoon of sesame paste to boost the flavor.

Why did my mochi turn out hard instead of chewy?

This usually means the dough was overcooked or dried out during steaming. Check that your water is boiling vigorously before you start, and make sure the lid is tightly sealed with no gaps for steam to escape.

How do I grind black sesame seeds without a food processor?

Use a mortar and pestle or a spice grinder in short pulses. You want a coarse powder with some texture, not a paste. A coffee grinder works perfectly if you have one dedicated to spices.

Do I need to refrigerate leftover mochi?

No, refrigeration actually makes them hard and unpleasantly chewy. Store at room temperature in an airtight container away from direct sunlight. They’ll maintain their ideal texture for up to 3 days.

Storage & Serving

Store these at room temperature in an airtight container for up to 3 days — refrigeration will firm them up too much. If you need longer storage, freeze individually wrapped pieces for up to 2 months and thaw at room temperature for 30 minutes. Serve them as an afternoon snack with green tea, add them to a dessert platter alongside fresh fruit, or dust with kinako (roasted soybean powder) for an extra layer of nutty flavor.

These chewy little rounds prove that simple ingredients can create something truly special when treated with care — make a batch and watch them disappear.
