Ever since I saw a âverticalâ cake (a thin sheet cut in 3â strips, then layered standing up with ganache around the inside of a cheese cake pan) I have been thinking of turning my tiramisu vertical. It was a little challenging to do the first outer layer, as the biscotti kept falling in, a smudge of mascarpone fixed that. I like the result very much! I do need to use an 8â instead of 10â pan, as it took 6 packs of biscotti instead of 4, it was HUGE and I didnât have enough filling⦠Vertical tiramisu it is!
