Questions
How many grams is a teaspoon of baking soda?
A US teaspoon (4.9 ml) of baking soda weighs 4.6 g and a 5 ml teaspoon about 4.7 g. A quarter teaspoon is therefore a little over 1 g.
How much baking soda per cup of flour?
About ¼ teaspoon of baking soda per US cup of flour is typical when the recipe has an acid. More gives a metallic taste and a brown, coarse crumb.
What is the difference between baking soda and baking powder?
Baking soda is pure sodium bicarbonate and needs an acid to release gas. Baking powder is baking soda plus a dry acid, so it works on its own. See the baking powder page.
Is bicarbonate of soda the same as baking soda?
Yes. “Bicarbonate of soda” is the British name, “bicarbonate de soude” the French and “Natron” the German. They are the same food-grade substance.
How can I check that baking soda is still active?
Add a pinch to a little vinegar or lemon juice. If it fizzes right away, it is active.
A US teaspoon of baking soda weighs 4.6 g according to the USDA, and a 5 ml teaspoon about 4.7 g. Baking soda is measured by the teaspoon, usually a quarter or half of one.
It only works with an acid in the recipe, such as buttermilk, yogurt, lemon juice, brown sugar or natural cocoa.
