Growing up, my mom taught me to always break an egg in a small glass Pyrex to check all over for blood spots, including peaking underneath the little dish. In the rare occasions when an egg had blood, the egg would be tossed out and I’d get a new one.
For anyone who is new here, fyi, I grew up in a less observant household. Later on in life, I noticed that many people [read less observant and non-Jewish] just break their eggs into the pan, bowl, or whatever dish they need to use it for, in cases where they don’t need to break one egg at a time exclusively to beat or whatever [gosh doesn’t it sound violent in this context?].
It turned out that my mom taught me halacha, something her mother taught her, and I found that out many many years later when I learned more about kashrut. I love my mom. Pretty cool 🙂
Thanks!
