I just moved into a new house with a lovely five-burner gas range (I've been wanting that fifth burner for so long!). The only problem is that the burners, even on their lowest setting, are very hot and make it impossible to do any low-heat cooking. I can't even make rice the normal way (only the pasta method works). I'm also concerned about them ruining my non-stick pans. A Google search revealed heat diffusers, something I'd never heard of before. Has anybody used them? Are they the answer to my problem? If so, any recommendations as to type and brand?
