howdy what is this called and where can I purchase a used one please.
I do believe that is a steam jacket.
around the middle. The kettle in the first picture may be jacketed all the way to the rim.
I see, was neglecting to add the jacket part in my search. I was just looking under steam kettle. Thanx for your time.
could you please check my Q about bagel in the general section please? Looks like you are pretty experienced in making. Thanks.
That looks just like the boiler I used to use 25 years ago when I was a bagel baker. Just a giant pot essentially. Ours was gas fired with thick insulated walls made from stainless steel.
