But, proper storage is key to keeping your devilled eggs fresh for a longer period. You see, when you store them in a sealed container in the fridge, you're creating a barrier between the eggs and any bacteria or contaminants that might be lurking in the fridge. This will help keep your devilled eggs safe to eat for a longer period, typically 3 to 5 days.
Now, you might be thinking, "But what about the mayo and mustard? Won't they go bad quickly?" And to that, I say, yes and no. While it's true that mayonnaise and mustard can be breeding grounds for bacteria, if you're using fresh ingredients and storing them properly, you should be okay. Just make sure to give them a good sniff test before serving, and if they smell off, it's best to err on the side of caution and toss them.
Think of it like this, when you buy a carton of eggs from the store, they usually have a sell-by date on them. This is because eggs are a perishable item, and if not stored properly, they can go bad quickly. It's the same with devilled eggs, they're just a bit more delicate because of the added ingredients.
