Every person who loves baking knows how important it is to know the difference between baking soda and baking powder. Both of these substances are some of the most widely used leavening agents which are responsible for the expansion and rise of the batter or dough.
These rising or leavening agents impart your baked goods a very high volume along with a smooth texture and crumb and that is why you need to know how and when to use these in your recipes.
For this purpose, knowing the difference between baking powder and soda is very crucial and that is what we will be focusing on in this article.
Here is all you need to know about the difference between baking soda and baking powder:
Baking Soda VS Baking Powder: Differences
For the success of any recipe, you need to first master proper ingredient measurement techniques. Though both baking soda and powder work on the same principle, they are still not interchangeable. Both these leavening agents react with other baking ingredients to form carbon dioxide which upon expansion provides the lift in your baked goods.
The main difference between the two is in their chemical composition. The baking soda consists of sodium bicarbonate which is an alkaline salt that has a white powdery appearance. Upon reaction with an acid, it produces carbon dioxide.
On the other hand, baking powder is a mixture of sodium bicarbonate with an acid such as cream of tartar, and sometimes a starch. This substance needs a certain amount of heat and moisture to produce its effect.
When to Use Baking Soda
Since there is no acidic constituent in baking soda that is needed for carbon dioxide production, it is mostly used in recipes that feature acidic contents.
It is most commonly used in making baked goods that include, yoghurt, molasses, chocolate, brown sugar, cocoa powder, or buttermilk in their recipes and the ones that need a certain level of browning such as cookies.
You can also use baking soda in cosmetics and skincare applications. Many people believe it to be effective as a part of deodorants and toothpaste. Baking soda mixed with water is found to be effective in treating acidic reflux. Its alkaline pH effectively neutralizes stomach acidity just like an antacid.
When to Use Baking Powder
You can use baking powder when working with recipes that do not contain an acid as a significant ingredient. You can use it to make muffins, scones, biscuits, pastries, bread, and plenty of other such recipes.
Since baking powder is activated with both moisture and heat, many manufacturers label it as “double-acting”. When you mix it with a liquid, it immediately starts to form carbon dioxide. After that when you start heating the batter, the process continues giving your baked goods the much-needed expansion.
Baking Powder and Baking Soda Conversions
It is a well-known fact that baking powder is a weaker leavening agent than baking soda. Baking soda is about 3 to 4 times stronger than baking powder and that is the reason why in most recipes only about 1/4 teaspoon of the former is used per cup.
Some people make the mistake when measuring ingredients and use the same amount of baking powder and baking soda for the same recipes. This results in tasteless and flat baked goods. If your recipe demands baking soda but you have baking powder available or vice versa, you can follow the conversion tips given below to proceed.
How to Convert Baking Soda into Baking Powder
If you need baking powder for your recipe but you don’t have it at the moment, you can use baking soda as an alternative. Just make sure to use it in a very small amount since it is a much stronger leavening agent.
Typically, about 1/4 teaspoon of baking soda gives you an equivalent effect to 1 teaspoon of baking powder.
Since baking soda lacks acidic content and you need a reaction between acidic content, alkaline baking soda, and water to get the leavening action, it makes it necessary that you add acid in the recipe where you replace baking soda with baking powder.
You can try using 1/4 teaspoon of baking soda plus 1/2 teaspoon of cream of tartar if you don’t have baking powder. You can also use 1 teaspoon of lemon juice or white vinegar if you don’t have cream of tartar.
When you use lemon juice or vinegar, it can lead to a tangier taste which you can eliminate by adding 1-2 tablespoons of sugar.
How to Convert Baking Powder into Baking Soda
The conversion of baking powder to baking soda is a little easier. In order to get the same leavening action, you will need to use 3 to 4 times more baking powder. If your recipe needs 1 teaspoon of baking soda, you can triple the amount of baking powder with the help of a digital kitchen scale and use it instead.
Recipes where baking soda is needed already have an acidic element to neutralize the baking soda and create air bubbles for expansion.
How to Check if Either Has Gone Bad?
Before you use baking soda or baking powder, it is better to check their potency. If you store these in an open container, both these substances stay fine for about 6 months. After that, they might lose their potency and go bad.
If you already have baking soda or powder at home but you are not sure whether it has gone bad or not, it is better to use the following tests to verify.
In order to check baking soda, take a teaspoon of it in a small bowl and add a tablespoon of lemon juice or vinegar to it. If it bubbles and fizzes violently, it means it is still usable. If it doesn’t, throw it away.
To check baking powder, add 1/2 teaspoon of it into a bowl and then pour 1/4 cup of boiling water over it. If the mixture bubbles vigorously go ahead and use it in the recipe and if it doesn’t then you know what to do.
Conclusion
Both baking powder and baking soda are among the vital baking ingratiates. Despite their similarities, it is still not wise to use these interchangeably. They are different in their chemical composition and leavening strength and that means you need to be careful when replacing these with each other in the recipes.
Knowing the difference between these two can help you use them better in your baking recipes. Using these leavening agents the right way can help you get the desired results in terms of color, taste, and texture of your baked goods and that is why you need to learn as much about them as possible.
