The season is brief for these tart treats and aficionados know to get 'em while they can. Grown in the Hudson Valley, NY, these sour cherries have a unique sparkling taste when cooked down with sugar. The resulting compote is used to make powerful sauces and intensely flavored cherry pies, cocktails, sorbets, and preserves in the European tradition. Use right away as sour cherries have a short shelf life - they a rare and fleeting treasure.
