Instructions
Wash your tomatoes and basil with water.
Heat water in water bath.
Cut the tomatoes in 2-3 pieces, depending on size. Only remove stems, you will use a food mill after processing.
Add the remaining ingredients into the pan with the tomatoes and put on medium heat.
Stir every few minutes so it does not burn on the bottom.
The tomatoes will start to breakdown and juice will escape from the tomatoes.
Allow to cook 1 1/2 - 2 hours to become soft and falling apart. You will want the tomatoes to break down and softened. This will allow them to process in the food mill easier.
Heat up water in the water bath canner, so it's same temperature as the sauce.
Place the tomato sauce into a pan and cook to reduce the sauce by half.
Once to the consistency you want, remove from the stove and process the tomato mix through the strainer.
Place the sauce into sterile jars and wipe the rim with a clean wet towel.
Place a lid and band on, finger tight.
Put the jar into the water bath canner. Repeat process.
Process the jars 35 minutes for pints, 40 minutes for quarters (this is based on Michigan elevation, adjust if needed).
Turn off the heat and allow the jars to sit for 5 minutes before removing from the water.
Remove the jars from the water and cover with a towel to cool for 12 hours.
Remove the bands to confirm that the jars have sealed.
