There are a few options for how to go about getting your egg bites cleanly out of the jars once cooked. In our kitchen, we like to place the toppings right in the jar and eat from the jar using a spoon! They are super easy to store and transport this way.
If you prefer to remove the bites from the jar, one suggestion is to remove them immediately after cooking; running a thin knife around the jar first to loosen the bites might help this. Another tip we’ve seen is to first grease the jars (using cooking spray, butter, etc.) to help them come unstuck more easily. Finally, many of our users-turned-egg-bite-aficionados recommend using silicone molds (such as this one) for quick and painless removal. Sadly, we have not tested these methods in our kitchen, so we are not able to speak with certainty on any cook-time changes that might be necessary with a change in container. If you have a Facebook account, we’d highly recommend checking out the Cook With Joule Facebook group for additional tips on egg bites.
