In the past I’ve been a little snooty about the duck confit and opted for a bit of mutton or lamb but I have to admit that I've changed my mind. It does bring a certain unctuosity to the party so it’s quack quack all round. Ham hock isn’t traditional either but as the excellent Felicity Cloake pointed out in The Guardian, it replaces both the cured meat and pigs skin so it’s oink oink there too.
The number of times you break the crust and stir in the bread crumbs is also the subject of some debate. A slightly wet, rather than claggy, cassoulet is much easier, and more enjoyable, to eat so stirring once, followed by a light sprinkling of crumbs before the final bake is perfect.
Its not exactly traditional because it brings a bit of smokiness into the mix but our Montbeliard sausage would also a good addition.
