often think about how there's not much left to be discovered. I remember thinking in high school math class, "How hard could it be to figure out that a squared plus b squared equals c squared? If I were alive in 500 BC, would it have be called the Saretsky theorem?"
Preheat the broiler. Slice the scallops in half horizontally. Spray two small or one large gratin dish lightly with cooking spray. Arrange the scallops in a single layer in the dishes, and season with salt.
Mix the lemon zest, cilantro, and panko together in a small bowl. Sprinkle over the scallops.
Mash together the butter, ras-el-hanout, and harissa in a small bowl. Place one dollop of compound butter on each scallop.
Sit the gratin dishes on a rimmed baking sheet, and broil until the panko is crisp and the scallops are opaque, 10 minutes. Serve right away.
