Should I rinse chicken livers before cooking them?
You should prepare the chicken livers by trimming away any fat, sinew, etc. You shouldn't need to rinse them, but it's OK to do so. Just be aware any time you are washing chicken or chicken parts that the bacteria can get all over your sink and kitchen, so I generally just confine to the cutting board and then wash it with warm, soapy water or put into dishwasher.
