Question about disk bottom pans
I found this site about 2 months ago; the wealth of information is amazing.
I read over and over about people burning food around the edges of their disk bottom pans (Sitram seems to be involved in many of these complaints) because the disk doesn't extend to the edge of the pan. This confuses me because I thought the purpose of having the heavy aluminum or copper disk was to conduct heat and get the pan hot since stainless steel by itself is not a good conductor of heat. If the ultimate heat occurs where there is no disk, then what is the purpose of the disk in the first place?
