My position is that we still should not reopen. The guideline does not say that questions with the same answer are never duplicates, it says that the fact that two questions have the same answer is not sufficient to say that they are duplicates.
We don't want to have tons of questions which have some apparent difference, when the difference does not matter and both questions describe the same problem. This has been a Stack Exchange policy since the infamous "programming on a boat" example. Here on Cooking, we have had hundreds of questions about leaving meat at unsafe temperatures. Frankly, if we decided to accept each of these questions as a different one, and not close a "left out steak for 16 hours on the counter" as a duplicate of "left out roast for 17 hours on the table", I think the site would lose much of its value as a focused provider of information.
Now, I understand how a person who does not know the general lines of food safety cannot know that the animal source of the drippings is not a factor in the keeping time. The OP can reasonably have assumed that his or her question could get answers different from the pork drippings questions.
But somebody who comes here to ask the community for an answer obviously assumes that they know less about the topic than our community. So it is our call to judge whether there is a factual difference between this question and old ones, or not.
It is true that I closed this question alone, as happens so often, because we don't have enough active members with sufficient reputation to cast close votes. In this case, I felt knowledgeable enough about the topic to be certain that there is no real difference between the beef and pork dripping questions. And there will be no value in information content gained either for the site or for the OP if we leave the question opened.
If somebody feels that my knowledge is wrong, and there is a difference between pork and beef drippings storage time, please vote for reopen and explain your reasoning here. Also, if somebody thinks that my interpretation of the rules, as outlined in this answer, is wrong, please join the discussion.
