Boil fettuccine. Make sure it is ready at the same time as mussels and clams, otherwise it will get gluggy.
I suggest using a big fry pan and lid because in this pot it became a jumble of shells and some of the meet fell out while stirring. Fry shallots, chilli, garlic in olive oil.
Add muscles and clams, cover with lid for 5 min or until shells open. I used some of the juice the mussels and clams came with. Add butter and half a glass of wine.
I put in fettuccine in first and seafood on top. There should be plenty of delicious juice. Use fresh French stick to enjoy and mop up juice. Enjoy.
