What You Need to Know
The process relies on amylopectin gelatinization at 70–80 °C, where starch granules swell and release amylopectin into the liquid, forming a colloidal emulsion. Gradual addition of preheated broth maintains a steady temperature, preventing starch breakdown. Butter and Parmigiano‑Reggiano introduce fat and protein that stabilize the emulsion, enhancing mouthfeel.
