My very yummy potato salad, which tastes a lot like my deviled eggs – but with potatoes!

Try to purchase fillets that are of similar size, and avoid those that weigh less than 5 ounces because they will cook too quickly. A nonstick skillet ensures that the fillets will release from the pan, but for the sauce a traditional skillet is preferable because its light-colored surface will allow you to monitor the color of the butter as it browns.
