Why This Recipe Works
For our chicken kiev recipe, we focused on the biggest problem first: getting the butter to survive cooking without leaking. The answer was to butterfly the chicken breast—slicing it lengthwise, almost in half, and then opening it up to create a single, flat cutlet. We then placed a slab of herb butter on the cutlet and rolled it up like a burrito. Chilling the rolled cutlets for an hour in the refrigerator further sealed the seams, improving our chicken kiev recipe immensely.
