41 Handling Chemically Leavened Products
Mixes containing chemical leaveners can either be refrigerated or frozen as long as the temperature is below 5°C (41°F). Although some carbon dioxide is released during the first stages of refrigeration, moderately good results are obtained from mixes that have been refrigerated for a long period of time. Frozen mixes should be allowed to thaw slowly in the refrigerator before being used. To avoid moisture loss, the mix must be covered during refrigeration.
