Ingredients:
- 1 cup (200g) granulated sugar
- 1 cup (240ml) water
- 1 cup (240ml) freshly squeezed lemon juice (from about 6-8 lemons)
- 1 tablespoon lemon zest (from about 2 lemons)
- 1/2 cup (120ml) whole milk (3.25% milkfat)
- 1/4 teaspoon kosher salt
- 1 cup (240ml) lemon-lime soda (such as Sprite or 7-Up), chilled
Instructions:
- In a medium saucepan, combine sugar and water. Bring to a boil over medium heat, stirring until sugar is completely dissolved. Remove from heat and let cool for 30 minutes.
- In a large bowl, whisk together the cooled simple syrup, lemon juice, lemon zest, milk, and salt.
- Cover the bowl and chill in the refrigerator for at least 2 hours, or preferably overnight. This allows the flavors to meld together nicely.
- If using an ice cream maker, pour the chilled mixture into the machine and churn according to the manufacturer's instructions (usually about 20-30 minutes).
- Gently stir in the chilled lemon-lime soda after churning (if using an ice cream maker) or just before freezing (if not using one).
- Pour the sherbet mixture into a shallow freezer-safe container. Freeze for at least 2 hours, or until firm but not rock solid. Aim for a scoopable consistency.
