## Questions & Answers

**Q: Your description makes no sense. Do you have someone who speaks English write your description?**
A: Essentially you place this iron egg into your boiling water, soup, stew, sauce to add iron based minerals to add to the food. Same concept as people cooking in an iron skillet, it adds iron to the food for dietary purposes.

**Q: What happen to stainless pot if don't add drops of lemon juice/acid?**
A: Why do you use lemon juice when the recipe does not call for it?

**Q: Is this product made in Japan?**
A: Yes, this is made in Japan, a product of famous "Nanbu-Tekki" (Nanbu Iron).  This item is used for iron supplementation during the cooking.

**Q: Can this be used in a pressure cooker?**
A: I would not use this inside the pressure cooker…
I do not think it is safe.

*by く***ん on October 3, 2025*

ご飯を炊く時に一緒に入れて炊きました！効果はまだよく分からないけど良さそうです。 メンテナンスが大変で、炊き上がったお米がこびり付いてしまって洗うのが大変… きちんと水分を取らないとすぐサビます。
