I want a cocktail featuring rye whiskey and tropical fruit juice like lychee, passion fruit, or pineapple.

Based on your preference for rye whiskey combined with tropical fruit juices, there are several great options to consider. The two cocktails that feature rye whiskey and pineapple juice are "Red Pineapple" and "Rabbit’s Revenge." Both these options blend the rich, spicy character of rye whiskey with the sweet and tangy profile of pineapple juice, providing a delightful tropical twist to your drink.

Red Pineapple is a simple yet inviting cocktail. It combines 30ml of whiskey with a top-up of pineapple juice and a dash of grenadine, making it a refreshingly fruity cocktail with a vibrant red hue. It's perfect for those who enjoy a light and easy-drinking beverage with a subtle whiskey backdrop.

On the other hand, Rabbit’s Revenge offers a more complex flavor profile, combining 60ml of whiskey with dashes of pineapple juice and grenadine, topped up with tonic water. This cocktail is served in a highball glass and adds a hint of bitterness and effervescence from the tonic water, balancing the sweetness of the pineapple juice and the rich character of the whiskey. It’s an invigorating choice for social gatherings or a relaxing evening drink.

If you lean towards a more nuanced and layered experience, either of these cocktails would be an excellent choice. Cheers!
