In the low acid tomato sauce recipe, you use baking soda to neutralize the acid in the sauce. I was wondering, is it possible to use baking soda in other things like chili to do the same thing?
This is a difficult question to answer because the research that went into the recipe on the Dr. Gourmet web site for Low Acid Tomato Sauce was pretty extensive. I made dozens of batches of tomato sauce, testing different amounts of the baking soda for flavor (Dr. Gourmet is, after all, about the food first). After testing for taste, I then used a pH meter to find what amounts of baking soda would result in an acid neutral sauce.
The ratio that I found was 1/4 tsp. of baking soda per cup of sauce. At that point the sauce was nearly acid neutral and did not taste funny. The more baking soda that was used, the more of a soapy flavor there was.
My best recommendation for you, if you wish to try this, is to begin with less than the 1/4 tsp. of baking soda per cup and adjust upwards. Do keep in mind that using the baking soda does work as adding sodium so there is less need to add salt.
