1/2TablespoonDiamond kosher saltuse less if using other salt
1smashed garlic clove
1teaspoonsdried oregano
pinchred pepper flakes
2teaspoonsbalsamic vinegar
Instructions
The amounts in this recipe are flexible. Sauce is one of those things that you taste and tweak as you go along. Make it yours!
Starting with a cold pan, cut onion in half (stem to end) and place in a stock pot or sauce pan with the butter. Cook on low until the butter melts and let it go for a couple minutes more without browning the onion.
Add tomatoes to the pot, breaking up with your hands as you add them. Stir in remaining ingredients and simmer 1 hour, partially covered, stirring occasionally.
Taste. Adjust. Taste again. Remove 1/2 of the onion and the parmesan rind. Use an immersion blender to smooth out the sauce to your liking. You can also do this in a blender or food processor in batches (let it partially cool first if not using the immersion blender!)
Enjoy!
Notes
When I'm done with a block of parmesan cheese I put the rind in a ziplock bag and throw it in the freezer. The rind adds lots of flavor to soups, stews and sauce!
If you can find a #10 can and want to make a large batch, multiply the recipe by four. Freeze up to 4 months.
