One may also ask, how do you cut a round cake into a triangle?
Slicing Into Even Triangles. Select a knife that’s big enough to cut across the entire round cake. For example, if the diameter of your round cake is 10 inches (25 cm), your knife should be at least that long. If you’re unable to find a knife as long as the diameter of your cake, choose one that’s as long as possible.
In this regard, how do you line the sides of a round cake pan with parchment paper?
Similarly, which side of parchment paper goes up?
The shinier or glossy side of the parchment paper will be the one coated with the silicon, so this is the side that should be coming into contact with your food (and should therefore be the side that goes up).
