Eggnog: the boozy holiday sweater you drink. A festive concoction born from the unholy union of eggs, cream, sugar, and whatever bottle of booze your uncle reaches for first. Traditionally spiked with rum, brandy, or bourbon (or all three if you’re aiming for a sleigh ride straight to DrunkyTown), this yuletide classic feels like a dessert, a drink, and a dare all at once.
