Bitter Lush Slush

Gather all ingredients including a bitter-forward spirit or liqueur such as amaro or Campari, a tropical fruit juice like pineapple or passion fruit, fresh grapefruit juice, and a sweetener such as simple syrup or orgeat. Chill all liquid ingredients in the refrigerator beforehand for best results.

Measure and pour approximately 1.5 oz of your chosen bitter spirit, 1 oz of rum or tequila as a base spirit, 2 oz of tropical fruit juice, and 1 oz of fresh grapefruit juice into a blender. Add 0.5 oz of simple syrup or orgeat to balance the bitterness.

Squeeze fresh grapefruit or citrus over a strainer to remove seeds and pulp, then add the strained juice directly to the blender with the other ingredients. Fresh juice is strongly preferred over bottled for optimal flavor.

Add 1.5 to 2 cups of crushed ice to the blender on top of the liquid ingredients. Using crushed ice rather than cubed ice will produce a smoother, more consistent slush texture.

Blend all ingredients on high speed for 20 to 30 seconds until the mixture reaches a smooth, uniform slushy consistency with no visible ice chunks. If the mixture is too thick, add a small splash of juice or water and blend again briefly.

Taste the slush and adjust balance as needed, adding more sweetener if too bitter or a few drops of citrus juice if too sweet. Blend for an additional 5 to 10 seconds after any adjustments.

Pour the finished slush into a chilled tiki mug or hurricane glass. Garnish with a grapefruit wheel, a sprig of mint, a cocktail umbrella, or other tiki-appropriate garnishes.

Serve immediately with a wide straw to preserve the slushy texture. If preparing in advance, store in the freezer for no more than 30 minutes and give the mixture a brief stir before serving.
