Somehow, I forgot to take any photos of the sauce making, maybe, it was being covered (and covering the kitchen) by tomatoes.
I started with twenty pounds of Roma tomatoes. I purchased them for twelve dollars at the farm stand down the street.
I peeled them, by scoring the skin, placing them in a pot of boiling water for a minute then placing them in an ice water bath.
Once peeled I seeded and cored them. I saved the peels, seeds, etc. in a strainer over a bowl.
After the first few batches I roughly chopped two onions and four cloves of garlic and let them soften in my biggest pot with some olive oil, salt and pepper. Then back to the tomatoes. Once they had softened I added the tomatoes.
In another pot I put the peels, etc. once the strainer was full to cook the remaining flesh from the peels and cores. Occasionally smushing them with a wooden spoon.
Once all the tomatoes had been processed I added dried spices to the mixture: basil, parsley, oregano and marjoram. Then I let everything simmer for a very long time. After a while I took the pot with the peels and cores, and pressed out the sauce through a strainer. I did this in batches so that I could discard the remaining skin and seeds and get the most out of them. I added this to the big pot with the tomatoes.
After everything had simmered for hours I used a hand blender to break down the tomato flesh then let it simmer until it reached the consistency I wanted, adjusting the spices as I went. I canned four quarts but I probably made five and used one before they were canned.
