Yet another one of Molly Yeh's recipes! My husband, Drew, made this challah and it was amazing. We didn't really alter the recipe in any way (why  mess with perfection?), so I'm just going to link to Molly's  Scallion Pancake Challah recipe here so it's simple enough to recreate yourself! (It's also in her cookbook, Molly On The Range)—enjoy!
