Notes
Use freshly squeezed lemon juice whenever possible for the brightest, freshest flavor. Bottled lemon juice will work in a pinch, but fresh lemons make a noticeable difference.Don't skip the lemon zest. It adds an extra layer of citrus flavor and gives the sorbet its bold lemon taste.
Chill the lemon mixture completely before churning. A cold base freezes faster and creates a smoother texture.
Taste the mixture before freezing and adjust the sweetness if needed. Lemons can vary in tartness, so you may want to add a little more sugar depending on your preference.
For the best texture, store the sorbet in an airtight container and place a piece of plastic wrap directly on the surface before covering.If the sorbet freezes very hard, let it sit at room temperature for 5–10 minutes before scooping.
Serve in chilled bowls or glasses to help keep the sorbet frozen longer on hot summer days. For an extra-special presentation, serve the sorbet in hollowed-out lemon halves and garnish with a small mint sprig.
