My wife has bought a big bag of fresh mussels to put in a paella later, and we're not sure how best to cook them. My idea was to steam them in advance and then just add them to the paella to warm through. Do you just put them in a pan with a little boiling water (like 1cm) and wait for them to cook, or do you have to make sure they're just steamed rather than boiled?
Quick answers appreciated, we're paranoid that they'll all die and go off....
