🥘 Ingredients

• Gin:
  • Hendricks: Known for its unique infusion of cucumber and rose, Hendricks adds a refreshing and floral twist to your gin and tonic.
  • Tanqueray: This classic gin boasts a robust juniper flavor, complemented by hints of citrus and spice, making it a versatile choice for any gin cocktail.
  • Watermelon Gin: Enhance the watermelon flavor of your drink with a gin infused with natural watermelon essence, perfect for a summery twist.
• Watermelon Syrup: I’m using my homemade syrup, but store-bought works just as well.
• Tonic Water: Check the list below for the best options.
• Cubed Ice: Essential for keeping your drink perfectly chilled.

See the recipe card for quantities.

🔪 Instructions

Step 1: Choose Your Glass. The preferred glass for a gin and tonic is a highball glass, but a balloon glass works as well.

Step 2: Fill the glass with cubed ice to keep your drink perfectly chilled.

Step 3: Pour in your choice of gin (Hendricks, Tanqueray, or watermelon gin) and add the homemade or store-bought watermelon syrup.

Step 4: Top with Tonic. Pour tonic water into the glass, filling it up. A highball glass typically holds between 240 ml (1 cup) to 350 ml (1 ½ cups).

Step 5: Add a lime slice for a touch of citrus and insert a reusable drinking straw.

Step 6: Sip and savor your delicious watermelon gin and tonic!

Eco Tip: Think about the environment and use reusable straws instead of plastic.

💕 Perfect Pairing

• Strawberry Shortcake: Fresh strawberries and whipped cream add a delightful sweetness that pairs nicely with the drink.
• Watermelon Sorbet: A refreshing and light option that complements the watermelon flavor in the drink.
• Lemon Sugar Cookies: The tangy citrus flavor of lemon sugar cookies balances the sweetness of the watermelon syrup and enhances the gin‘s botanicals.
• Berry Pavlova: A light and airy dessert topped with fresh berries, which pairs well with the fruity notes of the cocktail.

🍸 Tonic Options

1. Fever-Tree Premium Indian Tonic Water: Known for its high-quality quinine and subtle botanical flavors, this tonic enhances the gin‘s complexity without overpowering the watermelon notes.
2. Schweppes Tonic Water: A classic choice with a crisp and clean taste, it balances the sweetness of the watermelon syrup nicely.
3. Q Tonic Water: Made with organic agave for a slightly sweeter taste, it pairs well with the fruity flavors of the watermelon gin.
4. Mediterranean Tonic Water: With hints of lemon, thyme, and rosemary, it adds a unique, herbaceous twist to your watermelon gin and tonic.
5. East Imperial Tonic Water: Offers a light, refreshing flavor with a hint of Thai lemongrass, perfectly complementing the watermelon and gin.
