Method
Make simple syrup
- Combine the granulated sugar and water in a saucepan and heat over medium until the sugar dissolves completely, about 5 minutes, then remove from heat.
- Let the simple syrup cool to room temperature, then transfer to the refrigerator until ready (cooling prevents iciness during churning).
Chill the lime mixture
- Stir the cooled syrup with the fresh lime juice, lime zest, and salt until fully combined and the mixture looks uniformly pale green.
- Refrigerate the lime mixture until very cold, at least 3 to 4 hours, so it churns thick and slushy.
Optional creamier texture
- If using it, whip the egg white to soft peaks, then gently fold it into the cold lime mixture in 2 to 3 additions.
Churn and freeze
- Churn in an ice cream maker for 20 to 25 minutes, stopping when the sorbet is thick and slushy.
- Transfer to a container, smooth the top, and freeze for about 2 hours until firm, with a scoopable texture.
Serve
- Scoop into chilled bowls or fill hollowed lime halves, keeping the surface smooth and bright.
- Grate a little extra lime zest over the top and garnish with fresh mint just before serving for a vivid aroma.
Notes
Pro tip: chill both the syrup and the lime mixture until very cold—this is what helps the sorbet churn evenly instead of forming large ice crystals. Refrigerate any leftovers up to 3 days (scoops best after sitting 5 minutes at room temperature); freeze for up to 1 month. Dietary swap: skip the egg white to keep it fully dairy-free and still intensely lime-forward.
