Boiling eggshells in a saucepan is a simple and effective way to sanitize them for various uses, such as in gardening (as a calcium supplement), composting, or even crafts. Here’s how to do it safely and properly:
🥚 How to Boil Eggshells in a Saucepan
✅ Supplies Needed:
-
Used eggshells (rinsed)
-
Saucepan
-
Water
-
Slotted spoon or strainer
-
Oven or baking sheet (optional, for drying)
🔥 Steps:
-
Rinse the eggshells:
-
Remove any remaining egg whites or yolk from the inside of the shells. You can rinse them under warm water. This helps reduce odor and bacterial growth.
-
-
Place eggshells in a saucepan:
-
Use enough water to fully submerge the shells.
-
-
Bring to a boil:
-
Turn the heat to high and bring the water to a rolling boil.
-
-
Boil for 5–10 minutes:
-
This kills any bacteria like salmonella and helps soften the shells slightly if you’re planning to crush them.
-
-
Drain and dry:
-
Use a slotted spoon or strainer to remove the shells.
-
Let them air-dry, or place them on a baking sheet and dry in the oven at 200°F (93°C) for 10–15 minutes to make them brittle and easy to crush.
