I simply sear my scallops to a golden brown (about one minute on each side on medium to high heat) and then dump my persillade on top. I also like to add a bit of lemon juice to give it an extra kick. To die for!! Note that scallops are like calamari: they have to be cooked quickly so they don’t feel like rubber in your mouth. Some people slice them in half before cooking them. I don’t because they end up being thoroughly cooked before they have enough time to brown on the outside.
