Not April Fool’s: I agree with Texas Gov. Rick Perry on something — the merits of derided “pink slime.” Dude, it is indeed beef — a source of low-fat nutrition. Ammonium hydroxide is safe and used in foods from cheeses to pudding. In my home, we rarely eat beef. But given that we’re not going to a meat-free society any time soon, I’d like those pushing the “yuck” factor to consider the extra 1.5 million or so head of livestock that will need to be slaughtered to fill the ground beef gap.
