Having someone in the family with acid reflux means you have to be careful what you cook. When I make spaghetti sauce and other tomato-based dishes, I usually add a bit of baking soda to neutralize the acid. But many people insist on another trick. You peel and cut a potato in half and then poke some holes in it. Add it to the sauce for 30 minutes, and when you remove the potato, it will have absorbed the acid.
