In a medium mixing bowl, combine the heavy cream and white sugar.

Using an electric hand mixer or a whisk, whip the mixture until it forms stiff peaks that hold their shape firmly.

Transfer the whipped cream to a piping bag and place it in the refrigerator to chill while you prepare the other components.

In a separate bowl, whisk together the glutinous rice flour, cornstarch, white sugar, and milk until the batter is completely smooth with no lumps.

Pour the batter through a fine-mesh strainer directly into a non-stick frying pan to ensure an ultra-smooth dough.

Add the butter to the pan. Turn the heat to low and begin cooking the mixture, stirring constantly with a spatula.

Continue to cook and stir until the mixture suddenly comes together into a solid, cohesive ball of dough that pulls away cleanly from the sides of the pan. This is the most important step.

Transfer the hot dough ball to a clean surface. Add the 3 drops of red velvet liquid and knead it into the dough.

Let the dough cool until it's safe to handle, then begin stretching and folding it repeatedly. Continue this process for a few minutes until the dough becomes very smooth, elastic, and no longer breaks when you pull it.

Lightly dust your work surface and hands with cooked glutinous rice flour to prevent sticking.

Pinch off a small piece of the pink dough and roll it into a ball. Use a rolling pin to flatten it into a thin, circular disc.

Gently press the disc of dough into a small, round mold or a shallow cup.

Pipe a layer of the chilled whipped cream into the bottom of the dough-lined mold.

Add one small spoonful of strawberry jam directly onto the center of the cream.

Pipe another layer of whipped cream on top of the jam, covering it completely.

Gather the edges of the mochi dough up and over the filling, pinching them firmly together to seal the mochi shut. Twist and pinch off any excess dough at the top.

Dust the bottom of the sealed mochi with a little more cooked glutinous rice flour.

On the top surface of the mochi, pipe a small decorative swirl of the remaining whipped cream.

Place one fresh strawberry on top of the whipped cream swirl as the final garnish.
