First, read the English article below.

Since this frosting has such a soft texture, it's easiest to apply it to the cake while the cake turns on the turntable. This reduces the mess and ensures an even, smooth application.  Turn the turntable to work on a fresh area as you finish the current area. Use a flexible icing spatula or round-bladed knife to quickly work over the entire frosting and leave it smooth, with tiny peaks here and there. Always hold a cupcake in one hand when frosting it. Place a dollop of frosting on the top. Use a round-bladed knife to swirl the frosting around the top. Try to do this in one continuous movement. As you swirl, push the frosting to the edges of the cupcake. Leave a peaked center and a swirled edge.
