Step 1

Mix cream and sugar in a small saucepan over medium heat, stirring until sugar dissolves and mixture just begins to simmer. Remove from heat.

Step 2

Meanwhile, in a small bowl, sprinkle gelatin over cold water and let stand until softened, about 2 minutes. Add to hot cream mixture, stirring until gelatin dissolves.

Step 3

Place mascarpone in a medium bowl. Strain cream mixture over top, stirring until smooth. Add rose water, and food coloring if using. Strain mixture into a large glass measuring cup or a bowl. Divide among four demitasse cups or 2-ounce ramekins. Refrigerate until set, about 2 hours (or overnight).

Step 4

Dip bottoms of molds into hot water to loosen, then invert onto plates. Divide lychees, raspberries, and candied ginger among plates. Garnish each with a rose petal if using. Pour 2 tablespoons reserved lychee syrup onto each plate. Serve immediately with ginger sugar cookies.
