How often should the box of Baking Soda in the fridge and/or freezer be changed?

Can I use Baking Soda from the fridge or freezer in my recipe?

Since an open box of Baking Soda naturally absorbs unwanted smells and odours, always use a fresh, unopened box to make the best tasting cookies and cakes.

What is the difference between Baking Soda and Baking Powder?

Baking soda is 100% pure sodium bicarbonate. Baking powder is a mixture of baking soda (usually about 28-30%) and various acidic ingredients (singularly or in combination). Both are used as leavening agents in baked goods- baking soda will react with an acid, giving off carbon dioxide gas and causing dough to rise. However, they are used in different situations and are not interchangeable. Baking soda is typically used in a recipe that has an acidic ingredient (cream of tartar, buttermilk, etc.) that will react with the soda to give off carbon dioxide. Baking powder, which contains one or more acidic ingredients to facilitate the reaction, is used in recipes without acidic ingredients.

How does the box differ from Fridge-N-Freezer™?

The baking soda in each is pure 100% sodium bicarbonate. The difference is in the packaging. Fridge-N-Freezer™ Pack is specially designed with removable front and back panels and cloth vents for maximum deodorizing power.

How does Baking Soda differ from Super Washing Soda?

Baking Soda is made of 100% Sodium Bicarbonate. Super Washing Soda is made of 100% Sodium Carbonate. While they sound similar, they are not the same.

Baking Soda can be used in baking, as a dentifrice and as an antacid, Super Washing Soda cannot. Super Washing Soda should never be ingested. Be sure to check product packaging for specific uses and recommendations.

How is baking soda derived?

ARM & HAMMER® Baking Soda got its start as a mined ore called trona. Trona is mined in the Green River Basin of Wyoming. Trona deposits were formed over four million years ago after the evaporation of great salt lakes in Wyoming, as well as in Kenya, Egypt, Venezuela, and the deserts of Central Asia. After trona is mined from these areas, the trona ore is heated to make soda ash (sodium carbonate), which is then dissolved in water. When carbon dioxide is bubbled through the solution under pressure, sodium bicarbonate forms and precipitates out of the solution.
