Close your eyes. Imagine sniffing a rosemary bush. That scent is bold, almost medicinal, like a forest after a rainstorm. Now imagine thyme: warmer, like dried flowers and a hint of clove. Which smell makes you think “steak night”?
If you’re grilling over charcoal or wood, go rosemary. It can handle smoke and fire. Thyme might just curl up and disappear in high heat. Think of it this way: rosemary is the campfire; thyme is the kitchen stovetop.
For a cast-iron pan indoors? Thyme is your reliable sidekick. Rosemary works too, but keep an eye on it—those needles can go from fragrant to bitter if they get too dark. Nobody wants bitter steak, my friend.
