The Hydration Phase
Combine: In a bowl, mix the milk, water lily seeds, rolled oats, and pitted dates.
Wait: Let the mixture soak for at least 1 hour. This ensures the oats and seeds soften enough to blend into a smooth cream.
Prepare the Mango Vessel
The Lid: Slice off the top 1/2 inch of a whole mango to create a "cap."
The Pit: Use a thin knife to cut around the central seed (pit). Carefully extract the pit using tongs, leaving a hollow cavity inside the fruit.
Create the Filling
Blend: Pour the soaked mixture into a blender. Add the milk powder, vanilla extract, and any mango flesh trimmed from the pit.
Smooth: Blend on high speed until it forms a thick, vibrant yellow, ultra-smooth paste.
Stuffing & Freezing
Fill: Place the hollowed mango upright in a small glass. Pour the blended paste into the cavity until full.
Seal: Place the mango "cap" back on top. Wrap the entire fruit tightly in plastic wrap.
Set: Freeze overnight (8–10 hours) until rock solid.
Slicing & Serving
Peel: Remove from the freezer and peel the outer skin with a sharp knife or vegetable peeler.
Slice: Cut the mango horizontally into thick, beautiful rings and serve immediately.
