@Andres Zapata Good quiestion Andres: It’s important, yes, but not exactly in the way people think. It’s true that collagen turns into gelatin, and that gelatin makes everything stickier, helping the rice adhere more to the metal. But that’s not really what we’re aiming for. What truly defines the socarrat is the caramelization of the starch. The starch is released from inside the rice as it cooks. Then, with a burst of heat, that starch caramelizes and forms the highly appreciated layer we call socarrat, which many people confuse with something burnt. But it’s the starch; not the gelatin produced by excess collagen. So it’s easy to mix them up, because collagen simply burns, and that “burnt collagen” is something completely different. They’re two distinct processes. Hope this helps Andres
