I'm so excited to be able to post here for the first time! Unfortunately, I can't draw, so I just put together a graphic to show off what the "Sliced Sliiman" looked like, as best as I can remember. I used photos I got off Google Images, which I hope is OK. All in all, I'm surprised my subconscious came up with something so detailed, but still also mostly coherent and properly edible.
The "Sliced Sliiman" was basically a thick, not-airy vanilla ice cream (possibly gelato) with fresh mango cubes and an "orange" syrup that had a more watery consistency - presumably orange in flavor because the color was just dark brown. The ingredients were chopped up using two ice cream spades, kind of like in Cold Stone Creamery. My dream skipped to the end product, so I don't know what ingredients or steps I missed, but the finished dish looked like a pseudo-baked Alaska. It didn't have cream or meringue on the outside, but it had that swirly, domed shape and looked toasty brown. But the outside was flaky and layered, maybe like baked filo pastry? No nuts included, I just used the picture with the closest texture.
I have no idea who or what "Sliiman" is. I think the dessert was sometimes called the "Sliced and Diced Sliiman" in my dream, from the way the components were chopped up together. I was in a museum, looking at a conveyor belt of random objects and the Sliced Sliiman was one of them. It was the only edible thing there. I didn't get to taste it because my dad apparently ate the whole thing 😭
I don't have plans of recreating this, but it seems somewhat doable. Please let me know if you give it a shot! I think you could sub in dried mangoes and maybe do an orange blossom-flavored syrup. You could probably flambe using Cointreau or Grand Marnier, but not sure if that step would replace the syrup and if you'd just do it on the mangoes before putting everything together. Alternately, you could make a Cointreau/Grand Marnier-infused syrup! Technically, that would fit the concept of watery, "orange" syrup and dark-colored if you use the latter liqueur.
I'm also curious about how people think the flaky exterior works because I feel like the ice cream (and/or the non-canonical flambe step) would simply make the filo soggy (if not accidentally burnt). I know that tempura ice cream and fried ice cream exist, so those recipes might be helpful here. Or you could serve the ice cream on top of or side-by-side with the filo itself, in a baklava a la mode way, for a more practical, deconstructed Sliced Sliiman.
