I don't think it's possible to make Homemade Spaghetti Sauce without making enough to feed an army.
When I was growing up Granny would always make a large batch of the BEST Spaghetti Sauce and stock the freezer with the leftovers. She made the best homemade Spaghetti Sauce I ever had, aside from when I was in about 2nd or 3rd grade, and wanted the plain sauce without all the stuff, like my friends ate. That phase of life didn't last long and I quickly realized plain tomato sauce wasn't all it was cracked up to be.
This one time in 6th Grade I spent the night at my friends house, the next day while their parents were gone we became hungry so we made Spaghetti Sauce, and not like you open a can of Ragu Spaghetti Sauce, we made a giant stock pot full of Spaghetti Sauce! I can't remember the outcome of making a giant pot of Spaghetti Sauce but hopefully their family enjoyed it as much as we did! I also can't remember if we cleaned the kitchen, but I sure hope we did.
I can only imagine the look on their Mom's face when there was enough Spaghetti Sauce to feed an army, and the kitchen looked like a bomb went off.. It's moments like those I look back on, laugh, and pray their Mom wasn't frazzled.
My Spaghetti Sauce making ways haven't changed after all these years, I still make a ton, and try to keep a few jars in the freezer for an easy dinner.
