That is approximately 1/5 of a teaspoon
To substitute baking soda for baking powder in a recipe, use 1/4 teaspoon of baking soda for every 1 teaspoon of baking powder called for in the recipe. Additionally, you may need to add an acidic ingredient like lemon juice or vinegar to help activate the baking soda.
To replace for example 3 teaspoons of baking powder with baking soda, mix 1 teaspoon of baking soda with 2 teaspoons of cream of tartar.
For 1 teaspoon baking soda you can substitute 1/4 teaspoon baking powder plus 1/2 cup sour milk or buttermilk to replace 1/2 cup of liquid called for in your recipe.
If you only have baking powder and a recipe calls for both baking soda and baking powder, you can generally replace the baking soda with additional baking powder. For every teaspoon of baking soda needed, use about 2 to 3 teaspoons of baking powder, but keep in mind that this may alter the cake's texture and flavor slightly. Additionally, since baking powder already contains an acid, you may want to adjust the recipe by reducing any additional acidic ingredients.
Baking soda is already an ingredient of baking powder so by mixing the two you would be simply changing the proportion of baking soda to baking powder. It will make no real difference to the outcome if you make up the volume of raising agent the recipe calls for with any proportion of baking powder to baking soda. As a safeguard you may like to add a teaspoon of white vinegar or a tablespoon of yoghurt or buttermilk to a cupcake recipe made with baking soda - the acid in the vinegar/yoghurt/buttermilk will react with the Soda to release carbon dioxide which will make you cupcakes rise.
You can add some baking powder, but it's not an ideal substitute; baking powder is a mixture of bicarbonate of soda (baking soda) and cream of tartar. This means you need to add slightly more than is baking powder than the quantity suggested for baking soda; usually around 1/4 teaspoon on top of the quantity suggested for bicarb.
I tried different amounts of baking soda and vinegar, and the 1 teaspoon of baking soda and the 1 teaspoon of vinegar which were the minimum amounts used in my experiment worked the best. I do not know the answer to your question, but I have the exact same question and I want to know the answer, too. May somebody please help me in this question. I researched about it, but I could not find any good or reasonable answer. Please help!!! Thank you very much!
I checked with a baking soda vendor and they explained that all baking soda is naturally gluten free. It is baking powder (which uses baking soda) that may contain gluten. You need to check with the manufacturer.
You can substitute baking powder for baking soda in a recipe, but the amount needed may vary.
You can substitute baking powder for baking soda, but keep in mind that baking powder is not as strong as baking soda so you may need to use more. Additionally, you can try a mixture of cream of tartar and baking soda as a substitute.
Substituting baking soda for baking powder helps the food to rise more, but also affects the flavor if you use too much. Baking soda begins to release bubbles as soon as it gets wet, so you lose rising power if you delay getting the batter into the oven. Baking powder (which may be called "double acting") has some ingredients that don't release bubbles until they are heated, so it is a little more forgiving. Baking soda helps reduce the acid in sour ingredients such as buttermilk, sour cream, yogurt, and molasses; that is why some baked goods have both. Usual amounts are 1/4 teaspoon baking soda per cup of flour or 1/2 teaspoon baking powder per cup of flour. Here is a lengthy article comparing the two: http://www.ellenskitchen.com/pantry/bsbp.html
Baking powder typically contains a negligible amount of carbohydrates, usually around 1 gram or less per teaspoon. It's primarily a leavening agent made from a combination of an acid (like cream of tartar) and a base (like baking soda), along with a starch to keep it dry. The starch may contribute some carbohydrates, but the amount is minimal in the context of a typical recipe.
