Lemon sorbet is a dairy-free frozen dessert of lemon juice, sugar and water.
Lemon juice and sugar syrup over crushed ice covers the flavor and gives up the texture, and the texture is half of what a sorbet was for. Another citrus sorbet gives the same cold aerated body and changes only the fruit.
Sherbet (North American)
Sherbet adds milk or cream to a fruit-and-sugar base, which softens the acidity and lightens the color. In a drink it reads creamier and shorter than sorbet. In a clear drink the dairy shows.
Lemon granita
Scraped ice crystals, not a churned smooth mass; it chills and sours the same way and will not whip, so it cannot make a Sgroppino.
Frozen and closed. Sorbet picks up freezer smells faster than ice cream because there is no fat to hold its own aroma in, so an open tub next to anything savory is a lost tub.
