Write the next sentence in this paragraph:

How to reduce acidity in cooking
Sprinkle small amounts of baking soda gradually into food during cooking to reduce the acidity in the food.
Taste the food often, until the tart flavor of the food is reduced. Baking soda is sodium bicarbonate, which is a form of salt.
If you are concerned about your sodium intake, add as little baking soda as possible until the food's tartness (and acid) is sufficiently reduced. Cook dishes for the shortest time possible so that water isn't cooked away and acid isn't concentrated in a smaller volume of food.
