My mom is 100% as was her mom (duh!) and she lived with us. Picked tomatoes the end of August and she canned her gravy. There is still one jar, she died 15 years ago and lived in a nursing home for about 10 years so that jar is an antique! My uncle was going to have it tested to see what she put in it but he died...
Anyways, no meat, meatballs yes and she made me a "special" read <gag> one with raisins. Yuck yuck yuck! Always hated that little meatball. Also sausage and sometimes brasole (can't spell it).
My grandmothers family is from Naples.
Actually meatballs with raisins and pignoli nuts is a Neapolitan tradition.
