Put it in a rectangular shape, covered with cling film, with a capacity of 1.2 liters. Put it in the freezer overnight. 10 minutes before serving, immerse the mold in hot water for a second and turn it onto a plate.
I poured it into a silicone mold (by the way, the best option), no need to cover it with a film, immerse it in water, everything is wonderful and pops out of the silicone mold quickly.
