I don't have a clue...

Okay... It is pronounced sham (as in sham) waaaa (as in waaaa) and set (as in set)... Sham-waaa'-set with the emphisis on the the waaa...

It's made from tomatoes and onions and peppers and celery and carrots and things and ya' kinda can them all up together to be used later in sauces, stews, casseroles, etc...

Yummy stuff and looks good in the pantry, too...
