How to Fix Acidic Tomato Sauce

Short answer

Grate half a carrot into the sauce and simmer 20 minutes — its natural sugar balances the acid without tasting sweet. A tablespoon of butter stirred in at the end also rounds it. Use a pinch of sugar if you must, and baking soda only in tiny amounts, since it flattens the flavor.

Fixes, best to worst

Grated carrot: half a carrot per quart, simmered 20 minutes. Invisible, and the traditional Italian answer.

Butter: 1 tablespoon per quart off the heat. Fat coats the tongue and mutes acid perception.

Time: 20 more minutes at a bare simmer. Much of the sharpness is under-cooked sauce.

Parmesan rind: adds savory depth that reads as balance.

Sugar: 1/2 teaspoon per quart. It works, but it makes the sauce taste sweet before it tastes balanced.

Baking soda: 1/8 teaspoon per quart, maximum. It neutralizes acid chemically and takes the life out with it.

Why the sauce got acidic

Canned tomatoes with added citric acid. Read the label and buy cans with tomatoes and juice only.

Tomato paste added raw. Always fry paste in oil for a minute until it darkens.

Not enough salt — under-salted sauce reads as sour.

Too much red wine reduced too fast.

Common questions

Does baking soda really fix acidic sauce?
Chemically yes, but it foams and dulls the tomato flavor. Use an eighth of a teaspoon per quart at most, and try carrot first.
Should you add sugar to tomato sauce?
Only if it needs it. Good canned tomatoes and a proper simmer usually do not.
How long should tomato sauce simmer?
A quick sauce, 20 to 30 minutes. Sunday gravy with meat, three hours at a bare bubble.
