Coq au vin is a dish of chicken stewed in red wine with pearl onions and mushrooms. It’s a classic French main dish. Another might be cassoulet, a hearty stew of white beans, pork, sausage, and confit of duck or goose.

Mousse au chocolat (chocolate mousse) was invented by the French. Another, fancier French dessert is Gateau St Honore: a base is made of pate brisee (basically a shortbread cookie), which is topped with a ring of pate a choux (cream puff dough). Individual cream puffs are filled with whipped cream, dipped in caramel, and affixed to the ring on the base. The center is then filled with creme Chiboust (pastry cream lightened with whipped egg white and stabilized with gelatine). It is complicated but delicious and very impressive.

I would recommend looking into Julia Child’s French cook book, it’s pretty solid.
