The dough for these orange-coconut macaroons is made in a food processor and dropped by teaspoons onto baking sheets.
Preheat oven to 300 degrees. Process granulated sugar and orange zest in a food processor until combined, about 3 minutes. Add almond paste; process 1 minute. Add egg whites, orange juice, confectioners' sugar, flour, half of the coconut, and the salt; process 1 minute. Remove blade, scraping batter into bowl with a rubber spatula. Stir in remaining coconut.
Drop rounded teaspoons of batter on to baking sheets lined with parchment paper, spacing about 2 inches apart. Bake macaroons until the edges start to turn brown, about 25 minutes. Transfer parchment and macaroons to a wire rack; let cool completely.
Macaroons can be stored in airtight containers at room temperature up to 2 days.
