Baking Soda Vs. Baking Powder

If you bake often enough, you will notice that some recipes call for baking soda, while others ask for baking powder. Both are  leavening agents used when you bake. What this means is that both baking soda and baking powder, when added to baked goods, produce carbon dioxide and cause them to rise or get fluffier. But each one brings a little something different to the party……

Baking Soda

Baking soda is just pure sodium bicarbonate. It is bitter and will add a bitter taste to your recipe unless paired with an acidic ingredient (buttermilk, honey, yogurt.) Baking soda, combined with wet ingredients and an acidic ingredient, like chocolate in your chocolate chip cookies, will kick off the chemical reaction of producing carbon dioxide bubbles. Once you add in the heat from the oven, your cookies will “rise” as the carbon dioxide bubbles expand in the heat. Since the chemical reaction starts right away, you need to bake right away. If you leave dough sit for too long, your baked good will be flat. It is usually found in recipes for cookies.

Baking Powder

Baking powder does contain sodium bicarbonate (yep, there is baking soda in your baking power.) But it also includes the “acidifying agent” (remember the chocolate?) in the form of cream of tartar. There is also starch that acts as a drying agent. Since it already has the acidifying agent in it, it will not be bitter if you fail to pair it properly with ingredients to balance it out. Baking powder gives you more time, as it can sit a little longer before being popped in the oven to bake. Recipes for cakes and biscuits usually call for baking powder.

Can you substitute in recipes?

You CAN substitute baking powder in place of baking soda. You will need more baking powder (2 to 3 times more) and it may affect the taste. Don’t use baking soda when a recipe calls for baking powder. Remember baking soda lacks the acidity. It has to be paired with an acidic ingredient in order to get it to rise. In a pinch, you can make your own baking powder, by combining 2 parts cream of tartar to one part baking soda. Or if you’re like me and bake a lot, just horde both baking powder and baking soda in your pantry!

How to test if your baking soda or baking powder are still good

Remember those baking soda volcanoes from elementary school? To test baking soda, put some in a small bowl and add a little vinegar to it. If it bubbles up, it’s still good.

The easiest way to test baking powder is to put some in a bowl and add some water to it. If it foams up, it’s still good.

 

 

Now that you know which to use and why, go get baking!!!

  1. That is actually something I have always wondered about! I sort of assumed they were completely different things with similar names, that could never be substituted… like soy formula and soy sauce. Do not give the latter to a baby, and do not put the former on your Chinese food!

  2. This was a very informative post! Thank you for sharing this 🙂 I found you via Good Morning Mondays and would love for you to share this at our weekly link up, the Art of Home-Making Mondays as well 🙂 Take care!

  3. THANK YOU!!! I was just researching this subject this past week. I love your simple explanations! I found this on Think Pink Sunday's linky party 🙂 Merry Christmas! PS…I can't wait to look at your blog more, it looks great! Sammi | Grounded and Surrounded

  4. I am always running out of baking powder so I use the substitution all the time 😉 I didn't know about testing it though, that's genius! Thanks for sharing at the Homestead Blog Hop, hope we see you there again this week.
