Rock and Rye Whiskey Liqueur

A traditional American whiskey-based liqueur built on straight rye whiskey blended with rock candy (or honey), aromatic bitters, and citrus peel — essentially a pre-batched rye old-fashioned. Typically 70-84 proof and noticeably sweetened compared to neat rye. Plays the role of base spirit AND modifier simultaneously in cocktails, so swapping it with plain straight rye loses the sweetness/bitters/orange-oil character that defines the drink.
