If you’re one of those people who puts tomatoes in the fridge, you are going to want to stop. Now.
Sure, chilling a tomato will keep it looking fresh for a longer period of time than if you left it on the counter, but it will also drain all that earthy, slightly grassy, distinctive tomato taste...
As anyone who’s tried to befriend a baby knows, the very young are a tough crowd. In response to your solicitous babble, a baby might lock eyes with you. Just as likely, though, she’ll stare insistently into an empty distance, spit up, or dispatch you with a wail of protest.
New research suggests...
California this year became the second state after Hawaii to raise its minimum smoking age to 21. When the law took effect in June, state public health officials declared it would “literally be a life-saving measure.”
