Expired baking soda is nothing to worry about because, like some other baking ingredients, you can use it past its sell-by date.
Baking powder expired: what to do?
If your baking powder has expired – according to the best-before date – you can still use it. After all, this date is only a recommendation. As long as food has a shelf life, you should use it. In this way you save garbage and counteract food waste.
Unsealed, dry foods such as baking powder can be kept almost indefinitely. So you can still use it months after the expiry date. However, once you open the packaging of the baking soda, its effects wear off after about a month.
For food of any kind, you can trust your senses. Take a close look at the respective product, smell it or try it. If nothing strikes you as odd, you can eat it. Anything that’s moldy goes in the trash.
Other baking ingredients: This is how long they can be kept
You can use your expired baking powder even after the best-before date has passed. The same applies to other baking ingredients. An overview:
Dry baking ingredients: Flour, baking powder, (vanilla) sugar and other dry baking ingredients can have a much longer shelf life than the best before date. However, one can distinguish again at this point:
Sugar can’t go bad. This is also the reason why it is often used to preserve foods such as jam.
In the case of flour and baking powder, on the other hand, the shelf life depends on the humidity as well as storage and packaging. Also, whole grains spoil faster because of their fat content.
Fresh baking ingredients: Fresh animal foods, such as eggs, are very delicate. Therefore, you should consume or process them as soon as possible. After the best before date has passed, it is advisable to heat the egg through. One method of finding out whether your raw egg is still good is an egg test: you put the egg in a glass of water. If the egg stays on the surface of the water, it is spoiled. You should also consume butter and milk in a timely manner. Tip: Animal baking ingredients often have a shorter shelf life than their plant-based alternatives. So feel free to use vegan margarine, aquafaba as an egg white substitute, and plant drinks as a milk substitute so that you can bake something with it for longer.
Nuts and Almonds: Whole nuts keep longer than grated ones. It is always advisable to smell the nuts and almonds and taste them if necessary. That way you can tell if they’re still good or not.
Chocolate and couverture: Dry and dark storage is important so that both chocolate and couverture last as long as possible. If you open the pack, it can be kept for another ten months, or up to 15 months for dark chocolate.
Spices: Spices should be treated in the same way as nuts and almonds, because whole spices such as cloves, cinnamon sticks or star anise have a longer shelf life than ground spices. Once you open the package of ground spices, you should use them within 6 months. Unopened, they will keep for about three years.
Tip: You can also freeze most fresh baking ingredients, vegan or not, to extend their shelf life.
