Combine sliced strawberries and sugar in a bowl and let them rest for 20–25 minutes so the berries release their natural juices and soften properly for blending.
Heat water, honey, and salt in a saucepan over medium heat for several minutes until dissolved completely, then allow the syrup to cool slightly before using it in the recipe.
Blend the strawberries, syrup, lemon juice, lemon zest, and vanilla extract until the mixture becomes completely smooth and evenly combined without visible chunks.
Chill the blended mixture in the refrigerator for at least 1 hour because colder mixtures freeze faster and create a smoother sorbet texture.
Transfer the mixture to a freezer-safe container and freeze for 4–6 hours, stirring every 45 minutes during the first few hours to break up ice crystals.
Let the sorbet sit at room temperature for several minutes before scooping so it softens slightly and becomes easier to serve cleanly.
