The Ruby Foo: A Modern Classic with a Tropical Kiss

There are some drinks that, upon first sip, transport you. They don’t just quench your thirst; they paint a scene, evoke a memory, or simply offer a moment of pure, unadulterated pleasure. For me, the Ruby Foo is one of those cocktails. I first encountered its vibrant allure on a sweltering New York City evening, seeking refuge in the chic ambiance of Ruby Foo’s. The bartender, with a knowing smile, presented this concoction – a shimmering ruby hue, crowned with a delicate lemon slice. The initial taste was a revelation: a perfect dance between the clean, crisp vodka and the subtly sweet, floral notes of plum sake, brightened by a whisper of tart cranberry and tropical pineapple. It was sophisticated yet approachable, a testament to the power of simple, well-balanced ingredients. This drink became my go-to summer refresher, a portable vacation in a glass, and a constant reminder of that memorable night.

Ingredients

The beauty of the Ruby Foo lies in its elegant simplicity. Each component plays a crucial role, contributing to a harmonious and memorable flavor profile.

• 1 ½ fluid ounces premium vodka (Ruby Foo’s famously used VOX, a choice known for its exceptional smoothness)
• 1 ½ fluid ounces plum sake (Look for a good quality, semi-sweet variety for the best balance)
• 1 fluid ounce cranberry juice (100% pure cranberry juice is recommended for a vibrant flavor and color without added sugars)
• ⅛ to ¼ fluid ounce lemon juice (Freshly squeezed is non-negotiable for that essential bright acidity. The range accounts for personal preference on tartness.)
• ⅛ to ¼ fluid ounce pineapple juice (This adds a subtle tropical sweetness and a lovely fruity undertone.)
• 1 thin lemon slice, for garnish

Equipment Needed

For this cocktail, the tools are straightforward, emphasizing technique over complexity.

• Cocktail shaker
• Jigger or measuring tool
• Strainer (Hawthorne or fine-mesh)
• Chilled martini glass

Instructions

Crafting the Ruby Foo is a swift affair, a testament to its status as a perfect after-work or pre-dinner indulgence. The key is in the proper chilling and shaking to achieve that signature smooth texture.

1. Begin by gathering all your measured ingredients. Accuracy is paramount in mixology, especially with delicate flavor profiles like this.
2. Fill your cocktail shaker about two-thirds full with ice. Using good quality ice that is not too small or watery will ensure proper dilution and chilling without over-watering your drink.
3. Add the premium vodka, plum sake, cranberry juice, lemon juice, and pineapple juice to the shaker with the ice.
4. Securely fasten the lid of the shaker.
5. Shake vigorously for approximately 10-15 seconds. You’re looking to thoroughly chill the mixture and aerate it slightly, which contributes to a silky texture. You’ll know you’ve shaken enough when the shaker feels frosty to the touch.
6. Strain the contents of the shaker into your chilled martini glass. This ensures no ice chips make their way into the final drink, maintaining a clean presentation and texture.
7. Finally, garnish your Ruby Foo with a thin lemon slice. A classic twist of the peel over the drink before placing it on the rim can also add a beautiful aromatic oil.

Expert Tips & Tricks

While the Ruby Foo is delightfully simple, a few chef-level touches can elevate it from good to exceptional.

• Chilling is Key: Always, always, chill your martini glass beforehand. Placing it in the freezer for at least 15 minutes, or filling it with ice water while you prepare the drink, makes a significant difference in maintaining the cocktail’s temperature.
• The Art of the Shake: Don’t be shy with the shake! A good, hard shake not only chills the drink but also emulsifies the juices slightly, creating a more integrated and pleasing texture. Listen for the distinct sound of the ice tumbling and rattling – that’s the sound of a perfectly chilled cocktail.
• Juice Quality Matters: As mentioned, using 100% pure cranberry juice will provide the most authentic and vibrant flavor. Similarly, freshly squeezed lemon juice is indispensable. The subtle sweetness of the plum sake is also a key player, so choose one you enjoy drinking on its own.
• The Splash Factor: The original recipe notes that ⅛ to ¼ fluid ounce of lemon and pineapple juice is a “splash.” This is about 1 teaspoon. If you’re using a standard jigger, the ⅛ or ¼ ounce marking is your guide. Taste and adjust after your first attempt if you prefer a tangier or sweeter profile.

Serving & Storage Suggestions

The Ruby Foo is best enjoyed immediately after preparation, when it’s perfectly chilled and its flavors are at their peak.

• Serving: Serve the Ruby Foo in a pre-chilled martini glass. The elegant glassware enhances the visual appeal and helps maintain the drink’s cold temperature. The garnish of a thin lemon slice adds a touch of freshness and a visual cue to the drink’s bright, citrusy notes.
• Storage: Cocktails are not typically designed for storage. Once mixed and exposed to air, the delicate balance of flavors begins to degrade, and the carbonation (if any were present) would dissipate. If you must prepare components in advance, keep the spirits and juices separate and chilled. The shaking and mixing process should always be done just before serving for optimal results.

Variations & Substitutions

While the classic Ruby Foo is near perfection, adventurous palates might enjoy these subtle twists:

• Fruity Infusion: For a slightly sweeter and more nuanced drink, consider using a white cranberry juice instead of traditional red. This will result in a paler, yet equally delicious, cocktail.
• Vodka Exploration: While VOX is a premium choice, experimenting with other smooth, neutral vodkas can subtly alter the drink’s character. Some prefer a slightly drier vodka, while others might enjoy a hint of grain or potato vodka.
• Sake Swap: If plum sake is unavailable or not to your liking, a dry Nigori sake can offer a creamier texture and a different, though still pleasant, flavor profile. Be mindful that this will alter the color and sweetness.
• Herbaceous Twist: For an added layer of complexity, consider muddling a few fresh mint leaves in the shaker before adding the liquid ingredients and ice. This introduces a refreshing herbal note that pairs beautifully with the fruit.

FAQs (Frequently Asked Questions)

Q: What is the “splash” mentioned for the lemon and pineapple juice?
A: The “splash” refers to a small amount, typically 1/8 to 1/4 fluid ounce (about 1 teaspoon), to add a touch of brightness and complexity without overpowering the other flavors.

Q: Can I make this cocktail in advance?
A: No, it’s best to make the Ruby Foo fresh just before serving. Shaking with ice is crucial for chilling and proper dilution, which can’t be replicated in advance.

Q: What kind of vodka should I use?
A: A premium, smooth, neutral vodka is recommended, like the VOX mentioned. This allows the other flavors to shine without being masked by a harsh alcohol taste.

A: Yes, the balance of tart cranberry, lemon, and subtle sweetness from the sake and pineapple makes it a well-rounded drink. You can adjust the lemon and pineapple juice to your preference.

Q: How do I get the perfect frothy texture?
A: A vigorous, well-executed shake with plenty of ice is key. This not only chills but also aerates the drink, creating a desirable silky texture.
