I sometimes make toast, but I also sometimes sear the bread.
It is thought that eating burnt bread is bad for health.
Above all, it tastes bitter and bad.
However, there are some effective way to use burnt bread.
In fact, the burn bread has “deodorization effect” and “dehumidification effect.”
If you put it in a refrigerator or a room, it will provide functionalities of dehumidification and deodorization.
Also, it is organic matter even if it’s burnt black, so you can use it as fertilizers.
