Baking a cake? The list of ingredients shows baking powder or baking soda or both. But what exactly are these two ingredients? The resemblance in name, similar in looks, used in baking, anybody can easily get confused as to whether they are the same thing or different? If they are the same then what are the similarities? And if different, then what is the difference between baking soda and baking powder?

This post tells you how these two similar-looking ingredients are different and whether there is any similarity between the two, as I strongly believe in the mantra: Know Your Ingredients, And, Be A Smart Baker. It is really important to have the right understanding of each of these as this can make a huge difference to the quality of your bakes.

What is Baking Soda?

Tip: If I am using both baking powder and baking soda in a recipe then as a rule of thumb, I use 1/4 teaspoon of baking soda for every one cup of flour.

 

What is Baking Powder?

Role of Double Acting Baking Powder

  1. Nowadays, for commercial purposes, double-acting Baking powders are available which contain more than one acid salts, which are both slow-acting and fast-acting acids.
  2. These slow and fast-acting acid salts release carbon dioxide at different levels of the baking process. 
  3. Some gas is released at room temperature while you mix the batter but the majority of the gas is released at high temperatures when the food is being baked.
  4. This means that the batter rises for a longer period of time, making lots of bubbles thus fluffier cake, muffins etc.

Tip: If I am using both baking powder and baking soda in a recipe then as a rule of thumb, I use 1/2 teaspoon of baking powder for every one cup of flour.

FAQs

 

Q. What is the purpose of baking soda in baking/cooking?   

A. Baking soda is used in cooking as well as baking. It makes the baked products light and fluffy. You steam Besan dhokla without baking soda and it will be hard and dense. The same dhokla, when steamed after adding baking soda, turns out to be super spongy and soft. The same is the case with baked goods especially eggless cakes. 

 

Q. Why Baking Soda Is Added To Eggless Cakes?

A. When we use eggs in baking then only baking powder is added and they do not require any baking soda as eggs are sufficient to lighten and leaven the baked goods.

In the absence of eggs, we use either baking powder or baking soda or both to achieve the sponginess and fluffiness in cakes. Baking soda, when activated, release bubbles of carbon dioxide that further expands under oven temperatures, causing baked goods to rise. In order to activate baking soda, just ensure that adequate acid, be it curd or vinegar or buttermilk or applesauce or lemon juice is added to it.

 

Q. What is the purpose of baking powder in baking?

A. Baking powder is used only in baking and it rises and expands the baked goods. Whether eggless baking or with eggs, baking powder cannot be avoided except for some exceptions like Vegan Chocolate Muffins

 

Q. Can I bake an eggless cake without baking powder?

A. Yes.  In that case, use baking soda only but ensure that you also use some kind of acid so that baking soda is activated and gives rise and fluffiness to the cake. My Chocolate muffins recipe does not have any baking powder.

 

Q. Can I Use Baking Powder Instead Of Baking Soda?

A. No, if you use Baking powder instead of baking soda then your baked goods will have a softer texture, less color, and will be acidic.

Q. Can I Use Baking Soda Instead Of Baking Powder?

A. No, if you use Baking Soda instead of Baking Powder then your baked goods will taste bitter and also won’t rise much. Why?

 

Q. How To Substitute Baking Powder and Baking Soda?

 

Q. Why Baking Soda is added in very little quantity?

A. Baking Soda is added in very little quantity. This is because if too much baking soda is added without having enough acid to react with ( activate it) then there will be unreacted soda leftover which will give a soapy or bitter flavor. So now you know why at times your cake or instant idly or dhokla tastes of soda.

 

Q. Why Do We Use Both Baking Soda And Baking Powder in a Baking Recipe?

A.There are two reasons for this:

 

Q. How to Check The Expiry Of Baking Soda?

A. Put little, maybe 1/4 tsp Baking soda in a bowl and pour 1/4 tsp Vinegar on it. If the bubbles appear, means it is active. Go ahead with your baking. If not then go ahead to put it in the trash bin.

Q. How to Check The Expiry Of Baking Powder?

A. Put little, maybe 1/4 tsp Baking powder in a bowl and pour 1/4 tsp Water on it. If the bubbles appear, means it is active. Go ahead with your baking. If not then go ahead to put it in the trash bin.

Tips

  1. Keep them labeled as there are high chances of getting confused owing to their similar looks. 
  2. They both expire very fast. So, if you are not a regular baker or are baking after a long time then please check and ensure that they are not expired.
  3. Always store these in a cool and dry place.

  1. In the starting of your article you have written that Sodium Bicarbonate gives a crisper texture and hence it is preferred for cookies. While in the differences listed in the box, you have written that Sodium Bicarbonate gives softness while Baking Powder is much preferred for cookies.
    So is Sodium Bicarbonate better for cookies or is Baking Powder?

    1. Dear both baking soda and baking powder are used for making cookies.It depends on the recipe.When baking soda is added, cookies spread out more thus becoming crisp.cookies made with baking powder tend to be fluffier and softer than cookies made with baking soda.
      Also baking soda is used only when there is an acidic ingredient like curd or cocoa etc in the recipe otherwise not.
      Best is to follow the recipe.
