Oil and flour the baking pan, and line them with parchment paper.
Add mascarpone, maple syrup, orange zest, cinnamon and cardamom. Pulse for about a minute at 10 second interval to incorporate well, and make it smooth.
Strain the water and throw away the petals. Bloom the gelatin in this water.
Warm the gelatin just enough to melt it. Do not overheat it.
Add the gelatin in rabri mix.
Gently fold the whipped cream in the rabri mix.
Cut the laddoos into halves and arrange them in such a way that it covers the circular cake.
Pour in the mousse and put it in freezer for atleast 4-5 hours until set and frozen
Take it out and set the pan on a glass or back end of a turn table.
I only used 1 half of the cake. You could use the other half just to eat as is with your tea or coffee. If you would like to use both the halves then cut the edges of other half as well. Pour half the mousse into the pan. Place this other half of the cake on top and pour rest of the mousse into the pan.
If you do not have a blow torch, then wet the paper towel with hot water and squeeze it tight. Rub that warm paper towel along the ring of the pan just enough so the side of the pan slides.
Khoya is easily available in any Indian or international grocery store in the freezer section.
