What is the shelf life of our products? Baking Powder If you have an unopened can of baking powder, please reference the expiration date on the bottom of the can. This date is two years after the day it was manufactured. If you have an opened can of baking powder, please use it within six months. Baking Soda Baking soda can be stored opened or unopened for up to two years. If you are using the soda in your refrigerator, it should be replaced every 30 days. Corn Starch Corn starch can be stored unopened or opened until the date on the bottom of the can. How do I know if my baking powder is still good to use? There is no easy test for determining the acceptance of baking powder beyond the use-by date on the bottom of the can. If your baking powder has been opened for more than 6 months, it may not have enough leavening action to leaven your recipe. You can test a small amount of powder in warm water to see if it fizzes, however, this is not a definitive way to test your powder. The baking powder may have enough leavening action to react in the water, but may not have enough to leaven a cupcake. If you are not sure how long your can has been open, we recommend replacing it so that you can avoid preparing a recipe that doesn’t leaven. How should I store my baking powder? Baking powder, soda or corn starch should be stored in a dry cupboard away from heat and excess moisture. You should only measure with a dry utensil and replace the lid promptly after each use. If you use a utensil that has any moisture on it, you can cause a reaction inside the can and your baking powder may not work properly. Storage in a refrigerator or freezer is not recommended, as the condensation from your refrigerator can also cause moisture to form inside the can, causing a reaction. What is the difference between baking powder and baking soda? Baking soda is pure bicarbonate of soda also known as sodium bicarbonate. It is an alkaline ingredient, and when mixed with acidic ingredients, it reacts and releases bubbles of carbon dioxide. Baking soda is single acting, it only reacts once it is combined with moisture. It has baking and household uses. Baking powder is used for baking. It is made up of sodium bicarbonate (baking soda); an acid salt which reacts with moisture or heat, or both – such as tartaric acid, mono-calcium or combination of acid salts; and cornstarch (used to keep ingredients separated). Baking powder is double acting, it reacts once when mixed with moisture and again when it is exposed to high temperatures. Are Clabber Girl products Gluten-Free?

Why is the peanut-free logo no longer on Clabber Girl / Rumford / /Davis / Hearth Club (any of Clabber Girl brands) packaging? Clabber Girl has changed the testing process for raw materials that are received at the plant. Why was the allergen testing process changed? Clabber Girl initiated the process to test for peanut proteins when cookie mixes were being manufactured; the cookies were sold in schools and there was a greater concern among consumers over products that were finished goods (or close to finished goods). Clabber Girl ceased manufacturing cookie mixes in early 2014. How was the decision made to eliminate testing for peanut proteins and peanut-free logo? Consumer research was conducted with consumers impacted directly by a peanut and/or nut allergy. Only 1/3 of survey respondents read baking powder labels. Most shoppers participating in the study were concerned about finished baked products, significantly more than the baking powder as an ingredient. Most considered “product made in a nut-free facility” as a product safe to purchase. What steps does Clabber Girl take to ensure food safety?
