Swordfish With Potatoes


A well-written recipe isn’t just about getting a delicious dinner on the table, but about teaching smart cooking steps. Like in this quick swordfish and potato recipe: you’ll use one pot to first boil the potatoes and follow with the snap peas, and after whisking together the lemon dressing, you’ll use the citrus-streaked bowl to stir up the caper-flecked mayonnaise. These steps not only cut down on dishes, they create a muscle memory for the future. Note: Swordfish can vary in sustainability, so feel free to swap in another fish like cod or sea bass. Your fishmonger can help you determine the best pick.
