I recently decided to give up on the tons of paper towels that I would use every week to dry lettuce and buy the OXO salad spinner. It's great, but I just had a few quick questions about the best way to use. It sounds crazy but I've found that I have to spin for quite a while at least probably total of 5 or so minutes to get the lettuce dry. I quickly learned to chop it after it's dry as it seems to take longer with smaller sized leaves. Is this about how long it should take?
