Cream Of Tartar Vs Baking Powder: What’s The Difference?

Baking Powder

Baking powder is a common household ingredient available in the pantry. However, cream of tartar is rather uncommon, and not many people are aware of its origin and purpose.

What is the difference between the cream of tartar and baking powder? Although you can use one as a substitute for the other, however, there are a few differences.

Some of the differences include process, functions, use, shelf life, and storage.

Let’s see what exactly cream of tartar and baking powder is and how you can use each product. Read on to know more! 

Cream Of Tartar Vs Baking Powder: What’s The Difference?

Given below are some of the major differences between cream of tartar and baking powder.

Process

Cream of tartar is a byproduct of the wine-making process.

After the wine is drained from the barrel, what leaves behind is tartaric acid in crystallized form. Then the cream of tartar is made from tartaric acid. It’s purified to make it in a dry form that you can store in your home.

On the other hand, baking powder is made from the amalgamation of cream of tartar and baking soda. It works so well as a leavening agent because it has the properties of both items.

Baking powder became a huge hit in the 1840s because earlier people had less knowledge about yeast and how to manipulate it to make bread. So baking powder helped a lot at that time and the bread-making process started.

It was at this time that cakes such as Victoria’s sponge came into existence. These cakes are super light and soft to consume. The process is rather interesting. It takes you back to the origin of the product.

Use

A cream of tartar is a stabilizing agent. And if you use it in whipping creams or egg whites then it will create the ideal meringue and whipped cream.

Also, have you ever noticed that when you make caramel, the sugar starts crystallizing? Well, this happens because of the absence of cream of tartar. It stops the crystallization of sugar and you can have a perfect candy or caramel at home.

On the other hand, baking powder is a leavening agent hence, it helps in the rising of cake or any batter. Just be precise with the baking powder measurement because too much of it can collapse the cake and too little will leave it heavy.

Function

Although cream of tartar is a key ingredient in baking powder, their functions aren’t the same. They both can act as a leavening agent yet there are some differences in terms of their function. Below we have listed the functions of each product.

Cream of tartar functions:

  • Stabilizes whipped cream and egg whites.
  • Regulates the size of sugar and does not let sugar crystals form
  • Since it is acidic in nature, it gives a distinct tanginess to the dishes. It is specifically used in snickerdoodles. 
  • Interestingly, apart from its culinary uses, you can also use cream of tartar to remove stains, rust, and clean appliances. 
  • Moreover, if you add a pinch of it to boiling vegetables, it will help retain the color.

Baking powder functions:

  • Gives the batter aeration and lightness. The end result will always be soft and spongey cake. 
  • Since it already includes cream of tartar and baking soda, it acts as a perfect rising agent in cakes and bread. 
  • Baking powder works well with water and when you mix them, it reacts to release carbon dioxide bubbles which makes it a leavening agent. 
  • Baking powder is mostly used in baked goods. It does not act as a cleaning agent.

Shelf life

Cream of tartar has a shelf life of up to 2 years and then it can start to go bad. Although it can even last for up to 5 years, it requires precision and care on your part.

On the other hand, baking powder also has a shelf life of 1-2 years. It is always best to look at the expiry date of the product and follow that because the manufacturers know the best. 

Storage 

Keep cream of tartar at room temperature since it is sensitive to moisture. And consistent exposure to light and moisture can spoil cream of tartar and it won’t help the creams or cakes at all.

Baking powder can also go bad if it is left in heat, light, or moisture. And the best way to know if it is still fine is to add ½ tsp of baking powder to a pan and add a cup of boiling water. If it bubbles, then baking powder is still fine but if it doesn’t then, it is time to discard it.

This is a foolproof method to check baking powder at least much better than using it in a cake and the cake not rising at all.

Keep both the products in an air-tight container and at a place where there is no sunlight.

Can I Substitute Cream Of Tartar For Baking Powder?

You can substitute cream of tartar for baking powder but it does not work well alone. As we mentioned above, baking powder is an amalgamation of cream of tartar and baking soda, so it’s feasible to mix both to make DIY baking powder.

Bear in mind that you can also add in cornstarch if in case you are not using it right away. If you want to keep it for a couple of weeks then add in cornstarch. However, if you are instantly using it then, there is no need for cornstarch.

Cornstarch helps in keeping the baking powder dry. It does not let it clump, form crystals, and prevent it from reacting prematurely. We would advise you to make only a small amount of the batch because the store-bought baking powder is more stable than the homemade. 

Cream Of Tartar To Baking Soda Ratio

To make baking powder, there is a specific ratio that you have to follow. The ratio is 2:1, which means two parts cream of tartar and 1 part baking soda.

For instance, to make a teaspoon of baking powder, you’ll need ½ tsp of cream of tartar and ¼ tsp of baking soda. You can add in ¼ tsp of cornstarch or you can even completely skip it. Since it’s just a teaspoon of baking powder that you’re making, it’s best to skip it.

However, if you want to make more and save for future use, you should use cornstarch.
