1 tbsp butter {optional}
1/8 tsp baking soda {optional}

28 oz diced tomatoes, 45 oz tomato sauce, 2 tsp dried basil, 2 tsp dried parsley, 1.5 tsp dried oregano, 2 tsp brown sugar, 2 bay leaves
Bring to a boil for 1 minute (stir to prevent popping). Reduce heat to a simmer.
Place a lid slightly ajar on the saucepan to allow steam to escape. Cook down for 1-2 hours until it has reached your desired consistency.
{optional} Add 1 tbsp of butter, and cook sauce for an additional 15 minutes.
1 tbsp butter
{optional} Add 1/8 tsp baking soda, and stir well to combine. The baking soda will react with the tomatoes and cause a bit of foaming.
1/8 tsp baking soda
Salt & pepper to taste.

For best results: allow sauce to cool to room temp in the saucepan. Cover and refrigerate for up to 24 hours.
Transfer cooled sauce to freezer containers and freeze until solid.

Notes

Will keep in the freezer for 3-6 months.
Feel free to add any other veggies that you love.
Any meat you add needs to be fully cooked before being stirred into the sauce.
