A whiskey sour is a simple concoction of whiskey, lemon juice, sugar, and sometimes whipped egg whites. Improve the drink by toasting your sugar before adding it.

Toasted sugar, unlike brown sugar, is white sugar that's been caramelized through toasting, giving it a warm flavor and dry consistency without the added moisture from molasses.

To make it, add white sugar to a pan on the stovetop or bake it in the oven, ensuring a low temperature and stirring periodically to achieve caramelization without burning.
