Sometimes even a well-rested steak will lose juices when you cut into it. Sometimes a completely un-rested steak won't spill a drop. But as a general rule, resting meat for about one-third of its total cooking time guarantees that more juices will stay inside than on your cutting board or plate.
I wasn't meant to be a cook. It's a profession I accidentally fell into one summer between college semesters while looking for an easy job as a waiter. Nobody would hire me as a server, but one restaurant, in desperate need of a prep cook, told me that if I could hold a knife, I could have a job.
I take my daughter to the San Mateo farmers market every Saturday morning, and despite repeated advice to the contrary, I usually do it on an empty stomach. Bad mistake. I wind up buying far more produce than our small family can eat within a week, which means I'm constantly trying to figure out ways to pack more vegetables into a single meal.
