When going by their scientific names, cream of tartar is called tartaric acid or potassium bitartrate while baking soda is referred to as sodium bicarbonate or bicarbonate of soda. 

Cream of tartar is a byproduct of wine-making, found as little crystals formed inside wine barrels which are then collected and processed. 

Baking soda can be found as naturally-occurring crystalline compounds, often mined through nahcolite beds or deposits, or created through a chemical method called the Solvay process.

Basically, baking powder is a combination of one (1) part baking soda and two (2) parts cream of tartar. 

All of these ingredients can be utilized as leavening or raising agents. 

They react with the acidic components of batters, which produces air bubbles of carbon dioxide which in turn causes the expansion and rise of different foods such as cakes, bread, and other baked and fried products.

Baking soda is often partnered with acid components such as vinegar, sour cream, buttermilk, honey, and maple syrup. 

It is also used together with water when boiling bagels, cooking dry beans, and parboiling potatoes.

Cream of tartar also helps in stabilizing egg whites to form stiff peaks when whipped. 

It is also added to simple syrups to prevent sugar crystals from re-bonding and forming crystals. 

Moreover, cream of tartar affects the pigments in flour for them to have a whiter appearance.

What does cream of tartar taste like?

By itself, cream of tartar is a flavorless baking ingredient, similar to baking soda and yeast. 

However, when incorporated with other ingredients, cream of tartar does have a distinctive flavor with a particular acidic, tangy, tinny, and metallic feel to it.

Even if they are used in minimal quantities, you can identify this taste in Snickerdoodle cookies, meringues, angel food cake, and other light and fluffy pastries.

What is cream of tartar made out of?

This dry and white powdered substance is an acidic byproduct of winemaking formed from fermenting grapes into wine. 

Grapes are an organic source of this substance’s main component: tartaric acid, which is why it is aptly referred to as cream of tartar. 

What happens is that in the process of winemaking, grape juice sits and ferments. 

This precipitates the potassium bitartrate and leads to the formation of crystals on the inside of the barrel casks. 

These crystals are then collected, filtered, and purified to make cream of tartar.

Ways to use cream of tartar

Aside from being an ingredient, you can use while cooking, cream of tartar has other uses outside the kitchen. 

Cream of tartar acts as a repellent for ants, cleaner and polisher for shirt stains and appliances, and remover of rust.

How to store cream of tartar

Similar to other baking essentials, cream of tartar is highly sensitive to light, air, heat, and moisture build-up. 

The best spot to store your cream of tartar is within an airtight container placed in a cool, dry area. Here’s how to do it:

  1. Keep the cream of tartar on its original packaging. 
  2. Store it in a cabinet, cupboard, or pantry in your kitchen, preferably away from heat and moisture. 
  3. Use your stored cream of tartar within five years.

Secure that the location has a constant temperature, meaning do not move it near the stove, dishwasher, refrigerator, oven, or sink, as these places are ideal spots with the temperature and moisture that can grow germs, molds, or other organic matter.

You should also keep its label to know its best-by date and to ascertain its shelf life. 

Take note that it should be put in a jar with a tight lid, not in a paper container. 

Does cream of tartar go bad?

Unlike other kitchen ingredients, cream of tartar possesses a long shelf life. 

Just like other powdered substances, as long as it is kept away from contact with water, cream of tartar can last for a long time. 

To be safe, experts suggest that cream of tartar should be fully consumed within five (5) years. 

Cream of tartar should also be kept in a cool, dry place, secured in an airtight container, and away from any place that has direct heat, intense light, moisture, creepy-crawlies like insects or spiders, or rodent infestations such as rats. 

For cream of tartar, you will know if it is fresh in its look and smell if it appears powdery and white and has a slightly acidic smell.

How to tell if cream of tartar has gone bad?

As a safety precaution, cream of tartar has a best-by date on its label so that it can be utilized in its best condition. 

However, you might as well check if your cream of tartar had contact with water. 

If your opened cream of tartar forms some foam, it is recommended to use it within six (6) months. 

If molds or any other organic matter form, that’s a tell-tale sign to stop using the product. 

You should also stop using the cream of tartar if there are changes in the color, visible dark specks in the product, or an off and pungent odor.

However, if you failed to look at the visual cues, you might also check the results in your baked goods. 

Signs that your cream of tartar has gone bad include hard clumps that stay in one position, egg whites that are still runny and cannot stay stiff, or pastries that do not rise as high as one desires.
