01 - Combine fresh strawberries, coconut milk, maple syrup, vanilla extract, and salt in a blender. Process until completely smooth and no strawberry chunks remain.
02 - Transfer mixture to an ice cream maker and churn according to manufacturer instructions until thick and creamy. Alternatively, pour into a shallow freezer-safe dish and freeze for 2-3 hours, stirring every 30 minutes to break up ice crystals until scoopable consistency is achieved.
03 - Using a cookie scoop or spoon, portion ice cream into 8 equal balls approximately 1 1/2 tablespoons each. Place balls on a parchment-lined baking sheet and freeze until completely firm, at least 2 hours or overnight.
04 - Whisk together sweet rice flour, granulated sugar, water, and beetroot powder if using in a microwave-safe bowl until smooth and lump-free. Cover loosely with plastic wrap.
05 - Microwave on high power for 1 minute, then stir thoroughly. Return to microwave for another 1 minute and stir again. Continue microwaving in 30-second intervals, stirring between each, until dough becomes thick, shiny, and translucent, approximately 2.5 to 3 minutes total cooking time.
06 - Let mochi dough rest for about 10 minutes until cool enough to handle safely. The dough should remain pliable and warm but not hot.
07 - Heavily dust a clean work surface with potato starch or cornstarch. Turn out the mochi dough, dust the top generously, and roll to 1/4-inch thickness. Use a 3.5-inch round cutter or drinking glass to cut 8 circles. Keep circles separated with additional parchment paper to prevent sticking.
08 - Working quickly to prevent melting, place one frozen ice cream ball in the center of a mochi circle. Gently stretch and fold edges of dough around the ice cream, pinching to seal completely. Place seam-side down in a cupcake liner or small muffin cup.
09 - Repeat assembly process with remaining mochi circles and ice cream balls. Transfer assembled mochi ice cream to freezer and freeze for at least 1 hour to firm completely before serving. Store in an airtight container in the freezer for up to 1 week.
