Culinary Physics Summary: Thermal Mass vs Pan Steaming RUN STATUS: READY TO DROP

When cold marinated food touches the vessel, the boundary water immediately absorbs latent heat of vaporization (2,260 J/g). The Cast Iron Kadhai holds 990 J/°C of thermal energy in its 5mm walls; its interface temperature dips to 178.4°C, remaining comfortably above the 140°C threshold to drive rapid amino-acid carmelization within 2.4 seconds. In contrast, the thin Non-Stick Pan holds only 427 J/°C; interface temperature plunges to 98.2°C, submerging the food in trapped boiling liquid for 64% of the cooking cycle and delaying the Maillard onset to 18.6 seconds.

Vessel	Stored Thermal Mass	Minimum Interface T	Maillard Onset	Steaming Phase	Flavor Compound Ratio
Cast Iron Kadhai (2.2kg)	990 J/°C	178.4 °C	2.4 s	8.0 %	3.8x
Thin Non-Stick (0.48kg)	427 J/°C	98.2 °C	18.6 s	64.0 %	1.0x (Baseline)
