In a large saucepan saute the onion in the oil over medium-high heat
until golden brown. (7-10 min). Add all remaining ingredients , bring
to a boil, then reduce heat and simmer uncovered at lowest possible
heat for 4 hours. (This long cooking removes as much acidity as
possible from the tomatös). Puree sauce in 2, 3 or more batches to
prevent it spilling out of blender/food processor.
