You can use a silicone cake deep cake pan instead of a plastic wrapped bowl, and remove the bombe by turning the silicone pan upside down and pulling up the sides. No need to place in hot water for removal this way. Do not let each layer freeze solid before adding the next layer or the layers will separate when slicing for serving.
