How to dismantle the cake rack?

The first step to dismantle the cake rack is to close the edge. Use a spatula to make an angle of 30 degrees with the surface of the turntable, stick it on the bottom of the cake, rotate the turntable, slowly withdraw the spatula, and collect a circle of cream at the bottom of the cake near the surface of the turntable. In this way, when the cake is pried up later, the outside of the bottom edge will not be all burr-like. Step 2: Scrape off: Insert a spatula near the surface of the turntable into the bottom of the cake, and then rotate the turntable once to scrape off the cream at the bottom of the cake.
