When melting the butter, do so gently over a low heat to avoid browning. You can make this sauce last minute; it doesn't taste better after sitting for a while. The cracked black pepper adds pops of flavor, while the ground black pepper gives heat. When zesting a lemon, avoid the bitter white part of the lemon. The juice adds acidity to the butter sauce, and be sure to avoid seeds. Stir well before serving, and remind guests to do the same.
