I made spaghetti sauce from a new recipe and it came out too tart...does anyone know what i can add to get rid of the very tart taste......

sugar

That's my answer too!

cream -- it helps with the tartness and the acid

Sugar, preferably brown sugar, just add half a teaspoon at a time 'til it tastes right. My husband is Sicilian and that's how he makes his sauce.

Brown sugar, syrup or honey

I made a lot...i will try the brown sugar..hope it works..
it called for oregano. could that cause the sauce to be so tart??? i am not a Betty Crocker....I hate cooking. I have no imagination for preparing food...it seems like everything i make doesn't come out like it should...I would rather scrub down a wall rather than cook...so now you know why my sauce came out like this...thanks for the info. will let you know what happens tomorrow..do you think if i add more water it will help???????

You can also add cut up carrots, which will cut the acid in the tomatoes. I usually start at sauce by carmelizing a chopped onion- cook in oil until it browns- that makes the sugar in it come out. you can also add a little sugar at any point.

I use a pinch of baking soda. :-D

I vote for carrots.
