Cook your spaghetti according to packet instructions and make the sauce while the pasta is cooking,
Heat the butter and oil in a wide shallow saucepan or frying pan with a lid (for later) and fry the garlic and chilli for a couple of minutes before adding in the white wine,
Turn the heat up to full and throw in your drained, de-sanded clams and cook with the lid on until they open up (3mins approx),
Remove the lid and add in the lemon zest, juice and chopped parsley,
The clams in this recipe could easily be replaced with mussels.
