'1 (1,000-mg) vitaminutes C tablet (ascorbic acid), crushed to a powder with back of a spoon', '1/3 cup sugar', '3 Granny Smith apples (1 1/2 pounds), cut lengthwise into 1-inch-thick sticks', '6 medium celery ribs without leaves (1 pound)', '1/2 teaspoon wasabi paste or powdered wasabi', '1 to 1 1/2 teaspoons water', 'Flaky sea salt such as Maldon', '1 to 2 tablespoons fruity extra-virgin olive oil', 'Equipment: an electric juice extractor'
Put crushed vitaminutes C and sugar in a 1-quart container that will fit under spout of juicer. Using juicer, juice apples and celery into container. Spoon off foam and stir until sugar is dissolved. Pour into an 8- to 9-inch square stainless-steel or glass baking pan and freeze until partially frozen, about 1 hour. Scrape and stir with a fork, crushing any lumps. Continue to freeze, scraping once or twice, until evenly frozen, about 2 hours more. Stir together wasabi and enough water to make a pourable sauce. Scrape granita to lighten, then serve sprinkled lightly with sea salt and drizzled lightly with oil and wasabi sauce.
