I have been searching for a stovetop blech with no success. My electric warming tray (no dial or on/off switch) works great for Friday dinner but seems to cool off sometime during the night so it can't be relied on for Saturday lunch. As an alternative to my crockpot, I ordered the only stovetop blech I could find on line but it was very thin and burned through by the time Shabbos was over. (When I questioned this I was told that I shouldn't have used it on an electric stove).
Does anyone know where I can buy a basic heavy duty stovetop blech?
