Buttery Shrimp With Dill (Garides Me Ánitho)

Season the shrimp with salt and add them to the pan in one layer. Increase the heat to medium and sauté until the shrimp begin to color, about 1 minute. Flip the shrimp over, then add the lemon juice and mustard to the pan. Simmer for 20 seconds, then immediately reduce the heat to low. Add 1 tablespoon of the butter and swirl the pan to form a sauce. Continue to swirl the pan and add the remaining butter, 1 tablespoon at a time, until each tablespoon melts, to create a creamy, emulsified sauce, about 2 minutes.
