Frozen Boozy Arnold Palmer (Vodka, Tea, Lemonade Cocktail)

Bring 3 1/2 cups water to a boil in a medium saucepan. Remove from heat and add tea bags and sugar. Let steep 4 minutes. Discard tea bags and let cool slightly (you should have about 3 1/2 cups tea).

Divide 3 cups tea between 2 ice cube trays; chill remaining 1/2 cup tea. Divide 3 cups lemonade between remaining 2 ice cube trays; chill remaining 1/2 cup lemonade. Freeze until solid, 3–4 hours.

Blend lemonade ice cubes, 1/2 cup vodka, and 1/2 cup lemonade in a blender until smooth. Transfer to a spouted liquid measuring cup or pitcher. Rinse blender jar and add tea ice cubes and remaining 1/2 cup tea and 1/2 cup vodka; blend until smooth.

Tilt a large glass to one side and fill halfway with lemonade mixture. While slowly returning glass to upright position, pour in frozen tea mixture to fill glass and create a swirl. Garnish with lemon wheels.

Ice cubes can be made 3 months ahead. Transfer to resealable plastic bags and keep frozen.
