How to correct too-tart tomato sauce without adding sugar or sweetener

how to correct tomato sauce without adding sugar

“Unless you are using sweet, height-of-summer tomatoes, chances are your tomato sauce will taste more tart than you might like. Many recipes call for adding a pince of sugar… but sugar doesn’t eliminate the tartness; it just makes the sauce sweeter. Nevertheless, I did that for years until my scientist husband reminded me that the way to neutralize an acid is with a base. He suggested adding a pinch of baking soda to overly tart tomato sauce.

“It works like a charm. You don’t need much baking soda to have an impact, so start with a pinch. The sauce will foam briefly as you stir it in. Let the sauce simmer for a minute or so, then taste again. Add a little more baking soda if necessary. Be careful not to add too much or your sauce will taste soapy.”
