Steps to Make Lotus Biscuit Mousse Cake
1. Prepare the Base
- Crush the cookies into fine crumbs using a food processor or by placing them in a ziplock bag and crushing with a rolling pin.
- Mix the crumbs with the melted butter until the texture resembles wet sand.
- Press the mixture evenly into the base of a springform pan, creating a compact layer. Chill in the refrigerator while preparing the mousse.
2. Make the Mousse
- Prepare the Agar-Agar Mixture:
- Combine the agar-agar, sugar, and water in a saucepan. Heat over medium heat, stirring constantly, until the agar-agar is fully dissolved and the mixture starts to thicken.
- Cream the Butter and Lotus Paste:
- Beat the softened butter until creamy, then add the Lotus Biscuit paste. Mix until smooth and well combined.
- Whip the Egg Whites:
- In a clean bowl, whip the egg whites until stiff peaks form.
- Incorporate the Agar-Agar Mixture:
- Gradually pour the hot agar-agar mixture into the whipped egg whites while beating continuously. This step ensures the mousse sets properly.
- Fold in the Whipped Cream:
- Gently fold the whipped cream into the egg white mixture, followed by the Lotus Biscuit butter mixture. Combine until smooth and airy.
- Assemble the Mousse Layer:
- Pour the mousse over the chilled cookie base, smoothing the top with a spatula. Chill in the refrigerator for at least 2 hours, or until firm.
3. Prepare the Chocolate Glaze
- Melt the chocolate and vegetable oil in a microwave-safe bowl or over a double boiler. Stir until smooth and glossy.
- Allow the glaze to cool slightly before pouring over the chilled mousse layer. Spread evenly, letting some drip down the sides for an elegant finish.
- Return the cake to the refrigerator for another hour to set the glaze.
4. Serve and Enjoy
- Remove the cake from the springform pan, slice carefully, and serve. Garnish with crushed Lotus biscuits or a dollop of whipped cream for an extra touch.
