This bright and aromatic lemon sauce is a classic accompaniment for cakes, puddings, or simple biscuits. Its tangy freshness balanced with sweetness and spice makes it a memorable finisher for many comforting desserts. The use of freshly squeezed lemon juice and grated peel infuses it with vibrant citrus flavor, while the butter adds smooth richness. A touch of nutmeg provides subtle warmth, making it an elegant yet homey sauce rooted in American kitchen tradition.
