This strikes me as one of those stupid box-checking steps that serves no good at all. Your defense against litigation is not that you mumble magic words which have paranormal power to scare away the solicitors. Your defense against litigation is that nobody will sue you because your site tracks recipes. If for some reason someone should get very POed at you, you will send them a conciliatory email and refund all the money they paid, and that will be the end of it.
