I am thinking about making a leary biscit, I have 2 recepies, differing only in that 1 uses peanut butter, and the other uses cheese, I have 2 questions,

1. which is better for absorbsion, peanut butter or cheese?
and
2. will making a Leary biscit make the microwave smell, well, not like food?

also, I am considering nachos, would that make the microwave smell?

thank you and have a nice day!
