To build the layered melon domes, prepare 5 separate stacks on a baking tray lined with parchment paper.Begin by placing 4 6.5cm rounds to create the base, then season with a little sansho pepper and lime zest. Add a stack of 4 5cm rounds, season again, then add a stack of 4 3.5cm rounds. Season once more, then finish with a stack of 4 2.5cm rounds. Season one more time, then drape over one of the 7cm sheets. Each stack should have 17 layers in total (each size has 4 rounds, then you finish with a final larger round draped over). Repeat this process 4 more times, until you have 5 neat domes of melon. Cut each dome in half and set aside
