Popelini

After macarons, the chou—a cream-filled puff pastry—might be the most popular single-bite treat in Paris. This chain has 10 locations around town, and they sell choux in a huge range of flavors, like lemon, salted caramel, raspberry cheesecake, and seasonal specials like tarte tatin in autumn. Its Italian-leaning name stems from the old legend that Queen Catherine de Medici brought over an Italian pastry pioneer to perfect the bite-sized cream puff. And while you can, indeed, pop a whole one in your mouth, two bites may be best.
