Egg shells take a long time to break down, so ideally they should be crushed. Not a pleasant job, unless you follow this routine:
- Have a baking tray lined with used or reusable baking paper ready in the oven. Whenever you use eggs, put the shells in there.
- When you preheat your oven, the eggshells will dry and go brittle, making them very easy to crush.
- Put them in a jar until you have a few more.
- You can even put them in the food processor and get them chopped up finely.
There you go – it’s not that hard! Time to get set up.
