Purple Sweet Potato Mousse Cake

Overview

My husband is traveling to Sichuan and will come home tomorrow. I will make purple sweet potato mousse to welcome him.

First bake a 6-inch chiffon cake
Steam the purple sweet potato, peel it and mash it with a spoon
Pour in milk and mix well
Filter through a sieve to form a fine purple sweet potato paste
Add 20 grams of milk and diluted water to dissolve the gelatine powder
Add the light cream to the sugar and beat over ice until 8 centimeters
Pour in the purple sweet potato milk paste and gelatine milk, stir well, and the mousse is ready
Cut the cake into two pieces
Trim edges
Put a piece into the mold
Pour half of the mousse liquid
Put another piece
Pour in the remaining half of the mousse liquid, shake it until the surface is flat and place it in the refrigerator for more than 5 hours
Take out the mold, draw the pattern with a toothpick, and trace the pattern with buttercream
Finished product
