The exact results depend on the stove, cookware, and diffuser design, but the principle remains simple: spread and soften the heat.
A Useful Tool for Older Cookware
Traditional cookware wasn’t always designed for modern high-powered burners.
Cast iron, ceramic pots, enamel cookware, and other older vessels can sometimes benefit from slower and more controlled heating.
A heat diffuser can help reduce the intensity of direct heat reaching the cookware.
This is one reason these simple kitchen accessories have remained useful even as cooking technology has changed.
