What is a Whiskey Sour?
A whiskey sour is a classic cocktail dating back to the mid 1800’s. The original recipe called for whiskey, lemon juice, sugar and shaved ice. It’s not far off from what is commonly served today.
The key to a perfectly crafted whiskey sour cocktail is all about the balance of flavors. A great whiskey sour will have the warm notes baking spice from bourbon (or other whiskey) and citrus-driven tartness that is balanced with just enough sweet sugar or syrup. In modern mixology, this cocktail has seen a recent revival and is a common inspiration for new sweet-and-sour creations. Personally, we think this Strawberry Rhubarb Whiskey Sour hits all the desirable notes and balance, just right!
Somewhere along the line, some clever barkeep began adding an egg white to the cocktail tin. This egg white whiskey sour variation adds a frothy, creamy mouthfeel that has since gained in popularity. However, to keep this Strawberry Rhubarb Whiskey Sour recipe light and Springy, we omitted the egg white.
Furthermore, in England and throughout other parts of Europe, it is popular to substitute the whiskey for gin or brandy. We haven’t tested these adaptations on this recipe, yet. Nevertheless, we imagine the results would be quite good! Please, let us know if you decide to try a variation of this recipe in the comment below!
Strawberry & Rhubarb - A Duo of Springtime Superheroes
Once the ground thaws and the weather warms, nothing says Springtime like freshly-bloomed flowers, bountiful farmer’s markets and, of course, strawberry and rhubarb everything! The Springtime is one of our favorite times of year due to the abundance of freshly-grown, locally available produce.
The start of the Spring season, each year, is marked by glossy stalks of crisp, red rhubarb. This tart veggie is often paired with fresh strawberries in countless pies, tarts, sweets and desserts. In this recipe, we are celebrating the season with an ice cold cocktail! This Strawberry Rhubarb Whiskey Sour marries all the flavors and pleasure of strawberry rhubarb pie in a simple-to-make cocktail! Here’s how:
The base of this Strawberry Rhubarb Whiskey Sour is Strawberry-Infused Bourbon. This component is easy to make, but must be done ahead of time. To infuse your whiskey with strawberries, simply combine quartered strawberries with your bourbon of choice. Then, keep the strawberry-soaked whiskey in a cool, dark place overnight - or for up to one week. (The longer, the better!) Once infused, strain out the strawberries and your Strawberry-Infused Bourbon will be loaded with fresh berry flavor and be ready to be used in cocktails!
