What You Need to Know
Heat transfer occurs through convection in the water medium, creating a thermal buffer that prevents direct contact with heat sources. The water bath's high specific heat capacity (4.184 J/g°C) ensures even energy distribution while the phase change at 100°C provides automatic temperature regulation.
Essential for temperature-sensitive preparations where protein coagulation (custards), fat crystallization (chocolate), or starch gelatinization (sauces) require precise thermal control without hot spots. The technique prevents scorching, curdling, and separation in delicate emulsions.
