Combine flour, sugar and water together with a whisk/fork to form a liquid mixture. Steam for 15 minutes or until the dough has become firmer and more opaque. Transfer to a parchment paper dusted with cornstarch and let cool until warm to touch. Roll out into a 6 x 9-inch rectangle. Refrigerate for 15 minutes, or until completely cool.
Scoop out 12 balls of mango flesh with a teaspoon. Pat dry with a kitchen towel to remove excess mango juice. Dip each piece in coconut lemon sauce, then coat with shredded coconut. Refrigerate until ready to assemble.
Cut the rolled out dough into 12 equal squares. Working quickly with floured hands, place a coconut mango piece in the center and fold the corners of the dough inwards. Pinch the folds to secure, then gently roll the dough into a ball. Repeat with the other pieces.
Refrigerate for at least 15 minutes before serving chilled. Best eaten fresh, enjoy!
Notes
This mochi recipe has been adapted from Okonomi Kitchen's Tahini Chocolate Truffle Daifuku Mochi.*You can use brown/organic cane sugar, but it will cause the mochi to appear slightly brown.**Get my Coconut Lemon Sauce recipe here.
