I would just like to add that it is very important to use the flavoring ingredients. Surely do not omit the lemon peel, vanilla and rum according to your taste. In the resulting cake, these little things really do a lot and move yours a lot in front of the common desserts.
When I invented the cake, I came out of a cream according to my grandmother Jiřina, who was an unbeatable baker and a confectioner, so you who know what you have my cook you know him. The cake also has a bit of my family, heart, taste, and tradition.)
For some, it could be marzipan and work to discourage it, so I want to encourage you, encourage and reassure you that even without marzipan is the cake for it, it will simply be covered with only that delicious cream and will certainly be so unsurpassably good. Alternatively, add chocolate sauce or ganache instead of marzipan.)
Do not limit the size of the mold. I have chosen a narrow 18 cm to make the resulting cake higher because I like it and I find it more modern. If you care for an average of 24, it probably will not be on three layers, but just two and proportionally divide the cream. You can help yourself with that.) Do not bind anything and even drop the coffin with coffee or extra rum for more.
