These different silicone hemisphere molds can be used in tandem by first molding an ice cream half-sphere in the smallest mold, then placing that frozen half-sphere into ice cream made in the next-size mold, and so on, until you have a hemispherical ice cream mound with several layers.

Flexible silicone mold resistant to cold down to -76F (-60C) and heat up to 446F (230C), letting you bake a cake or make ice cream and get it out easily thanks to the non-stick property and flexibility of the mold. The mold's integral frame makes it stable, and its suppleness lets you push your baked or frozen product out from the bottom.
