Mintedpineapple juice evokes the drinks served by vendors on the beaches of easternBrazil.
Puree the pineapple in a blender until smooth. Pour puree through a fine sieve into a bowl; discard solids. Return half the juice to blender; blend with half the ice and sugar. Add half the mint; pulse to combine. Transfer to a pitcher; repeat with remaining ingredients. Stir just before serving; pour into ice-filled glasses. Garnish with mint sprigs, if desired.
