What is your biggest size pot? What size pot do you use to make your soup - and what if your were doubling or tripling your soup?? The largest pot I own is a lightweight blue and white dotted "lobster" pot - not sure it was necessarily designated for that but it is the only thing I use it for - it is too lightweight for good cooking. So discounting that one the largest pot I have is my old 8 qt Farberware. I would love a larger pot. Last week I borrowed my neighbor's "corn" pot which is a heavier stainless one (no name - seems to have a disk on the bottom) and seems to be about 15 Qts. It is a great size for me when I need to make soup for a crowd. What are your suggestions?
