I have a marble rolling pin that is EXACTLY like that one, where one of the wooden handles split many years ago. I don't bake, so I've never used it (I think my Mom gave it to me). Came across the rolling pin in a box in the basement last month and I've been debating tossing it in the trash, as I couldn't think of any other use for it .... and I bought a pounder just recently.
Try it out on ziploc'd BSCB. Takes me all of 30 seconds to get it exactly where I want it with the heavy rolling pin. I set my cast-iron skillet to medium on the stovetop, spray both sides of the flattened chicken with Pam spray, and cook for 6 minutes per side with some salt & pepper. Voila, perfect chicken!
This is useful in just about anything. Because it's pounded flat, once you cook it, you can tear it with your teeth (unlike a full-thickness piece of meat), so it works great on a sandwich. Or coat it with any kind of sauce (teriyaki, sweet & sour, BBQ, honey mustard). Slice it into strips for a salad. Throw it on some noodles & add red sauce on top, voila, delicious Italian dinner meal. One of my favorites is very simple - Thousand Onion Chicken. Caramelize some onions (just slice the onion, toss it in a pan until they get soft), pour them on a plate, put the chicken on top, and dump Thousand Island dressing over that. Sounds strange, but tastes amazing!
This trick solved the chicken-cooking issue for me. No more Struggle Chicken!
