Frozen Moscow Mule

Ingredients

• ¼ cup (packed) light or dark muscovado sugar or dark brown sugar
• 2½ tsp. finely grated peeled ginger
• 4 oz. vodka
• 3 oz. fresh lime juice
• Pinch of kosher salt
• 2 lime wheels
• A 1-pint glass jar
• 2 reusable straws

Steps

1. Stir together ¼ cup (packed) light or dark muscovado sugar or dark brown sugar, 2½ tsp. finely grated peeled ginger, and ¼ cup boiling water in jar. Secure lid and shake until sugar is dissolved, about 15 seconds. Let cool slightly.
2. Uncover jar and add 4 oz. vodka, 3 oz. fresh lime juice, and pinch of kosher salt; seal again and shake to combine. Freeze until ice-cold but not solid, at least 1 hour and up to 4 hours.
3. Transfer cocktail to a blender and add 2 cups ice. Purée on high speed until thick and smooth. (On a hot day you may need to add a few more ice cubes to thicken, but keep in mind that the more you add, the more diluted the drink will be.)
4. Divide cocktail between 2 highball glasses and garnish each with a lime wheel and a straw.
