for a while now, i've been noticing a single hot spot whenever i cook on my range (a bosch gas model). at first i thought it was my pans (mostly ss all-clad) - but upon closer inspection, it happens in any pan, always at the same point - regardless of where you turn the pan. i'm wondering if drafts from any number of sources are causing the burner to flare more in a certain point in its radius. does this indicate a problem with my burners or is this just inherent in a gas range? the bosch wasn't cheap - and it seems to be a very well-made unit. but this hot-spot thing is a bit of a letdown. thanks for any advice/information.
