Peel the Apple
Girls would peel an apple then throw the peel over their shoulder onto the floor or into a tub of water. The letter formed by the apple peel was the first initial of the man they would marry. I tried this once in my youth, but the dog always stole the peel before I could see the initial. I was once told by someone that if you recite the ABC's while twisting the stem on an apple, the letter you're on when the stem comes loose is the initial of the man you'll marry.
