Expiration & Storage Tips
When does dulce de leche expire?
Unopened, a store-bought jar of dulce de leche can last up to a year past the printed date if stored in a cool, dry place. This longevity makes it a handy pantry staple for occasional dessert enhancements. Once opened, it should be kept in the refrigerator and will stay good for about 2-3 weeks. If you've made homemade dulce de leche, you can keep it refrigerated for up to a week. While freezing is an option, it's not commonly done as it can slightly affect the texture, but if needed, it could extend the lifespan to about 3 months.
How do you tell if dulce de leche is bad?
If dulce de leche has gone bad, you may notice a number of changes. First of all, it might develop a darker color and hard, crystallized lumps. It can also develop an off smell - something fermented or sour, which is not typical of its usual sweet, creamy aroma. Finally, if you see any signs of mold, do not consume it and discard the product immediately.
Tips for storing dulce de leche to extend shelf life
• Always store open jars in the refrigerator. Unopened jars can be kept in a cool, dry place.
• Keep the lid on tight when not in use to stop any unwanted bacteria from contaminating your sweet treat.
• Use a clean, dry spoon for every serving to avoid introducing germs into the jar.
• If you won't use large quantities within the recommended refrigeration timeframe, consider freezing it in small amounts in an airtight container or ice-cube trays for single serves.
• Homemade dulce de leche should always be stored in the fridge and consumed within a week, as it lacks the preservatives found in commercially produced versions.
