Place the canned tomatoes in a bowl and crush them slowly by hand.
Heat your dutch oven or a large pot over medium heat. Add in the butter and continue to heat until it melts and foams. From there, add in the onions and a dash of salt.
Cover the pot and continue to stir until the onions are translucent and soft, about 15 minutes.
Add the garlic while still stirring, about 1-2 minutes. Add the tomato paste while stirring into the vegetables, about 5 minutes.
Pour in the red wine and deglaze the pot. Note and scrape any browned bits from the bottom of the pot.
After cooking for about 2-3 minutes, add in the hand-crushed tomatoes, salt, pepper, dried herbs, red pepper and cinnamon stick. Combine well!
Turn the heat up to medium high, bringing the sauce to a simmer. Reduce to maintain a steady simmer with bubbles. Now continue to simmer on low for 6-8 hours.
Continue to stir, once an hour while gently crushing the tomatoes with a wooden spoon. It’s done once the sauce has thickened and turned a deep red consistency.
