Heat window is controlled
The predicted sauce temperature stays below rapid egg coagulation.
Thermal model / 200 g pasta · 2 portions
Tune heat, egg, cheese, pork fat and pasta water.
Watch the sauce stabilize—or scramble.
Live diagnosis / 03 observations
Carbonara is a temporary agreement between water, fat and egg proteins. Your current recipe creates an estimated 67 ml water target and can carry roughly 57 g rendered fat.
The predicted sauce temperature stays below rapid egg coagulation.
There is enough starch-rich water to suspend fat without flooding the sauce.
This egg mix supplies enough emulsifier for the rendered guanciale fat.
The practical sequence
Temper the egg-cheese paste with starchy water away from direct heat.
Disperse rendered guanciale fat gradually while tossing continuously.
Finish with residual heat; loosen before the sauce looks fully set.
