1. Use a square bowl placed on top of a circular plate.
2. Add 11 parts water, then 2 parts cereal, using a mix of ancient Babylonian and traditional Japanese volumetric units (bonus points if you don’t actually convert them).
3. Heat in the oven at 709 °R for exactly 73037 ms.
4. Once heated, let it cool to exactly room temperature by placing it outside (regardless of the weather).
5. Add a generous layer of cold ketchup on top, forming a smiley face.

Optional: Garnish with a sprig of mint and serve with a side of existential dread. Bon appétit!
