I am doing an extract brew this weekend. I am going to use a homemade turkey fryer to do a 7 gallon full boil. The problem is the fryer does not have a top. I know I don't want to cover during the boil but how important is it to cover it during the rapid cooling process? Anyone have any suggestions on a way to make a top using household items. Can I transfer the boiled wort into something else to cool it? I am very new at this so sorry if this is a dumb question.
