Expiration & Storage Tips
When does Tiramisu expire?
Tiramisu is essentially perishable due to its dairy and egg content. If purchased from a store, it usually has a sell-by date which you should adhere to. As a general rule, once opened or if it's homemade, it should be consumed within 2-3 days. In the refrigerator, tiramisu retains its quality for that time before it begins to degrade. For longer storage, you may freeze tiramisu up to 3 months. Just remember, the longer the stored time, the drier it may become.
How do you tell if Tiramisu is bad?
Signs of a bad tiramisu are similar to any dairy-based product. If there’s a change in color, a sour smell extends beyond the coffee liqueur aroma, or signs of mold - this means it has gone bad. Additionally, a change in the texture like if it becomes excessively soft or having any slimy feel is an indicator it's no good.
Tips for storing Tiramisu to extend shelf life
• Use airtight containers for storing tiramisu in the refrigerator. Avoid using aluminum foil as it may alter the taste due to the metallic reaction with coffee and liqueur.
• If freezing, ensure that the tiramisu is tightly wrapped in layers of plastic wrap followed by a final layer of aluminum foil to prevent the entry of air.
• If you want to preserve the best taste and texture, avoid freezing and refrigerating tiramisu for long periods. It's always better fresh.
• Always remember to keep your tiramisu in the coolest part of your fridge, away from any foods with strong odors.
