Ingredients
2 inches peeled fresh ginger
2 pounds ripe red plums, halved, pitted, and coarsely chopped, plus thin wedges for garnish (about 9 plums total)
1 1/3 cups sugar
1/4 teaspoon coarse salt
1 teaspoon pure vanilla extract
Preparation
Pulse ginger in a food processor until finely chopped. Transfer ginger to a large saucepan. Add plums, sugar, salt, and 5 cups water. Bring to a boil over medium-high heat. Reduce heat to medium. Simmer, stirring occasionally, until sugar has dissolved and plums have broken down, about 15 minutes.
Pour plum mixture through a fine sieve into a 9-by-13-inch shallow nonreactive dish; discard solids. Stir in vanilla. Chill in freezer until edges are frozen, about 1 1/2 hours. Remove from freezer; scrape with fork tines, pulling from edges into center. Return to freezer. Repeat process every 30 minutes until mixture is the texture of shaved ice, about 4 1/2hours. Spoon into serving bowls, and garnish with plums.
