Save them for your garden! That's right, your tomatoes will love them. Grab a container and save them throughout the year. I recommend drying them first and than storing them; otherwise, you could end up with a rotten egg smell. I sit mine outside on sunny days to dry or stick them in the oven after cooking a meal to dry out. They don't need to be in the oven long or on a high temperature. Once cooled, crush them and put them in a plastic bag or container and store them in your freezer or the refrigerator. You can use a rolling pin to crush them.
Once garden season arrives, crush a few aspirin or calcium tablets and sprinkle it along with the crushed eggshells in the hole when you plant your tomatoes. I also sprinkle some around the soil once I get the tomatoes in the ground. I actually do this throughout the growing season. The eggshells will help give your tomatoes a calcium boost, and help fight off blossom end rot. It's also suppose to be a deterrent for slugs, cutworms and snails.
Do you use eggshells in your garden? How do you deter blossom end rot?
