Sweet and Sour Meatballs

The sweet in sweet and sour comes from a can of cranberry sauce and a handful of raisins, cooked down into four cans of tomato sauce. Three pounds of meatballs go in raw and simmer for three hours.

Grate the onions rather than chopping them. Grated onion disappears into the meat and keeps it tender, where chopped onion stays in pieces and the meatballs break along them. Matzah meal and breadcrumbs both work.
