I am considering getting a food steamer but I don't have access to a kitchen. I have a microwave in my room but I think I could use a steamer as well to cook vegetables. I've never used a steamer before and I won't be able to use it if it gives out a lot of steam due to damp issue.
Do steamers require ventilation? Or is it internally a closed system so nothing comes out? Can I use it in a closed room without having to open the window?
