a burner to hit the bottom of a pot directly, the metal surface acts as a buffer. This can reduce hot spots and make it easier to maintain a low, steady temperature.
For traditional cooking, that can make a significant difference.
Why Would Anyone Need One?
Not every dish should be cooked over high heat.
Foods such as sauces, stews, soups, custards, and slow-cooked dishes often benefit from gentle, consistent heating.
When a pot sits directly over a strong flame, the bottom can become much hotter than the rest of the vessel. This can cause food to stick, scorch, or cook unevenly.
A simmer ring provides an extra layer between the burner and the pot.
That makes it easier to maintain the kind of low heat needed for delicate cooking.
Particularly Useful for Slow Cooking
One of the biggest advantages of a heat diffuser is controlling the intensity of heat.
