Ah, January. Everyone is writing about getting healthy, eating kale, putting the bottle down and keeping the butter knife at bay. This post is not denying the value of any of that − I mean, who doesn’t love kale? But when the dark winter days start getting to you and you find your fingertips trembling over a stack of dusty takeaway menus, reach for a jar of this stuff. It’ll put a spring in your step and a smile on your face − it might be a pretty good cure for a stuffy nose too.
