To clean the mussels:

Drain the mussels, remove any beard, scrub with a brush or scrape off with a knife any dirt of growths on the shells. Soak in cold water till ready to put in the pot. Discard any mussel whose shell is not tightly shut.

To cook:
In a large stockpot, heat the butter and olive oil over medium heat.
Add onions and cook for 5 mins.
Add garlic and cook for about 3 more mins. till garlic golden  and onion translucent.
Add all the other ingredients (except the mussels)  and bring to a boil.
Add the mussels, stir well, cover the pot, cook over medium heat for 3 mins.
Uncover, stir well, cover and cook for 3 more minutes.
Check to make sure mussels are cooked. (The meat will be attached only to one shell and not to both).
Pour into a large bowl and serve!
