In a small pot, bring the chicken broth to a gentle simmer over low heat.
In a separate skillet, melt half of the ghee and sauté the minced shallot and garlic until fragrant.
Add the arborio rice to the skillet, stirring for one minute to lightly toast the grains.
Gradually add the warm broth one ladle at a time, stirring constantly until the liquid is absorbed before adding more.
Once the rice is tender and creamy, stir in the frozen peas, lemon juice, and lemon zest.
Pat the scallops completely dry with a paper towel and season both sides with sea salt and black pepper.
Heat the remaining ghee in a cast-iron skillet over high heat until it begins to shimmer.
Sear the scallops for two minutes per side without moving them until a deep golden-brown crust forms.
Serve the scallops immediately over the warm risotto and garnish with chopped fresh parsley.
