Notes

The Boston Sour is a sophisticated take on the classic whiskey sour, with the egg white adding a silky texture and a luxurious foam on top. For the best results, use freshly squeezed lemon juice and a good-quality blended whiskey. The superfine sugar dissolves quickly, providing the perfect sweetness without graininess. If you prefer a less creamy version, you can skip the egg white.
