Orange Crush

Ingredients

• 2 oranges
• ½ cup sugar
• 1 oz. chilled club soda, plus more for topping off
• 1 tsp. acid phosphate
• 1 oz. orange syrup
• 2 dashes orange bitters (optional)
• Orange twist, for serving

Steps

1. Peel 2 oranges with a vegetable peeler; reserve peels. Juice oranges into a liquid measuring cup to measure ½ cup. Transfer juice to a blender and add ½ cup sugar. Blend until sugar dissolves, about 20 seconds—if you taste it, it should not be gritty.
2. Return syrup to liquid measuring cup. Express oil from reserved peels into cup and stir to combine. Pour into a resealable jar. Seal and chill until ready to use. Do ahead: Orange syrup can be made 6 days ahead. Keep chilled. Shake well before using.
3. Fill a Collins glass with ice. Add 1 oz. chilled club soda.
4. Combine 1 tsp. acid phosphate, 1 oz. Orange Syrup, and 2 dashes orange bitters, if using, in a cocktail shaker. Fill shaker with ice, cover, and shake just until lightly chilled, about 5 seconds.
5. Strain into prepared glass. Top off with more club soda. Garnish with orange twist.
