A traditional marinara sauce does not have sugar in it at all. Some believe you should add sugar to a meat sauce. I personally do not.
Marinara, although the Italian word means Mariners or sailors sauce, has no fish it is either.
It is a simple tomato sauce that includes:
San Marazano canned tomatoes, the 13oz can
4 cloves of garlic sliced thin
one small chopped onion
3 leaves of basil sliced thinly
and olive oil.
If you did put sugar in your marinara sauce my suggestion is you should start from scratch again.
another answer:
Some traditional marinara sauce recipes do indeed call for a very small amount of sugar, usually 1 to 2 Tablespoons. The need for sugar dates from the time when fresh tomatoes were used before commercially produced canned tomatoes were universally available, and would depend on the relative sweetness or acidity of fresh tomatoes that were used.
Depending on how much too much sugar was used, a tablespoon or two of cider vinegar might bring the sweetness / acidity back into balance.
Depending on how much sauce you want you can use soy sauce and add sugar to it until it has the desired sweetness that you are looking for
Add lemon juice or white vinegar. :-)
Add 1 teaspoon of white sugar for each cup of fresh tomato sauce. Not only does this sweeten the sauce quite nicely, it also reduces the chance of heartburn or acid reflux often caused by tomato based sauces.
Add more sugar, salt and tomato sauce.
You can add sugar to the puree and heat it just enough for the sugar to dissolve and then you have a sauce. If you want to flavor it differently, you can add cinnamon or lemon juice.
Raw peeled potato will draw sweetness from the sauce
As my great-grandmother says, "Put in as much suger as your concience will allow, then turn around and add some more."
Add some vinegar and sugar.
Baking Soda is used to neutralize the acidity of the tomatoes in spaghetti sauce. If there was too much baking soda added, you might be able to add a little vinegar or even better a red wine vinegar to raise the acidity of the sauce or add more tomato sauce.
Ketchup and CocaCola. You can add vinegar and brown sugar also
add hot sauce and sugar it works every time
I would add 500gm. of sauce.
