Yes, you can use expired almond. Almonds are a very shelf-stable food and will generally last for several months past their expiration date if kept in an airtight container. However, it is important to check the almonds for signs of spoilage before consuming them. Look for any discoloration or mold on the almond skins, as well as any off odors or tastes when you taste them. If the almonds look and smell normal, then they are likely still safe to eat. It is also important to keep in mind that with age, almonds may lose some of their nutritional value. They may not have as much protein or other vitamins and minerals as fresh almonds do. To get the most nutrition out of your almonds, it is best to consume them within a few months of purchasing them. Overall, expired almonds are still safe to eat but should be checked for signs of spoilage before consuming them.
