Recipe(tried): If it works for acid reflux, it works with tomatoes

Baking soda is sodium bicarbonate, very well known to fight heartburn, because is alkaline (chemically neutralizing acid). When I have a problem with acidic tomatoes (or anything else) I add a pinch of baking soda. Be careful, just a little pinch, and then another, if needed. If you add too much, it will taste bitter, so it's better to go very slowly and add more. In any case, if I over do it , I go back with a little acid (tomato sauce needs a little bit of acid) and add either lemon juice or vinegar, again, very little at a time.
It's basic chemistry, no secret whatsoever.
