Let’s talk about the “operating system” of a pizza: the sauce. In the stack of pizza engineering, the crust is the hardware (structure), the cheese is the GUI (user experience), but the sauce? The sauce is the kernel. It manages the acid-sugar memory allocation and bridges the gap between the bland dough and the fatty cheese.

For decades, the source code for this kernel has been stable: standard processing tomatoes, harvested at peak ripeness, with a pH strictly controlled between 4.0 and 4.5. But a new study published in Scientific Reports in February 2025 suggests a critical vulnerability is emerging in the supply chain. The culprit isn’t a software bug, but a geological one: Soil CO₂ Leakage.
