What You Need to Know
During simmering, proteins denature around 60–70 °C, releasing amino acids such as glutamic acid that contribute to umami flavor. Starch granules gelatinize in the same temperature range, swelling and thickening the broth. The combination of these reactions yields a thick, cohesive texture typical of pottage.
