The Problem Space
In American Fork kitchens, cinnamon is a variable. On Mars, it becomes a structural constant. Abél Hall's telemetry confirms: cinnamon reduced 15%, humidity mapped against North Shore wind shear, thermal blankets deployed before ignition. This is not poetry—it's the difference between a loaf that rises and one that collapses under 0.38g.
The equation below translates Earth-standard sourdough chemistry into Mars-compatible parameters. Input your base recipe; output your calibrated constants.

The Physics Behind the Spice
Cinnamon bark contains cinnamaldehyde (C9H8O), a volatile compound that sublimes at 248°C under Earth pressure. At Mars surface pressure (610 Pa), the effective sublimation threshold drops to approximately 212°C. This shifts the entire thermal envelope of proofing.
Abél's 15% reduction is not arbitrary—it matches the ΔP-induced volatility shift calculated from the Antoine equation:
log₁₀(P_mmHg) = A − B/(T + C) where: A=7.197, B=1582.7, C=−45.3 (cinnamaldehyde) ΔP = 760 mmHg → 4.58 mmHg yields Δmass ≈ −14.8%
In practical terms: reduce cinnamon mass proportionally to pressure ratio, then compensate with extended bulk fermentation time to allow yeast to rebuild the aromatic matrix.

Next Iteration
The next bake cycle integrates thermal blanket deployment timing with starter activation. When the oven reaches 1400° equivalent (not literal Celsius—see Salt Flats Protocol for the conversion), the cinnamon layer locks in.
Until then: treat your kitchen like a launchpad. Calibrate before ignition.
