Basically the subject says it all. I've never done it before, any pointers?

Also, looking to use the remaining ground egg shells in coffee and tea to neutralize the phytic acid content. My body appears to be super sensitive to phytic acid, but I really enjoy my morning caffeine - trying to have the best of both worlds. Anyone ever tried this?

I'd put dairy in my coffee or tea, although my body handles dairy horribly. I need something with calcium to neutralize the phytic acid so it doesn't pull minerals from my body.
