The Hot Soak: Place the puffed water lily seeds, cashews, pitted dates, farmer's cheese cubes, saffron, and cardamom in a large heat-proof bowl. Pour the hot milk over all ingredients.
Softening: Let the mixture sit undisturbed for 1 hour. This is critical for rehydrating the dates and softening the seeds to ensure a smooth blend.
The Emulsion: Transfer the entire soaked mixture (including the milk) into a high-speed blender.
Blending: Blend on high until the texture is completely smooth, thick, and resembles a rich, creamy custard. There should be no visible nut or seed fragments.
Molding: Pour the creamy paste into popsicle molds, Kulfi molds, or small paper cups. If using cups, cover with foil and insert a wooden stick.
The Set: Place in the freezer for 5–6 hours or overnight until the popsicles are completely solid.
Serving: To demold, dip the base of the mold in lukewarm water for 10 seconds. Gently pull the stick to release.
