Once the salsa is prepped, place a half cup or so of white wine in a large pot, cover with a lid and place on a high heat.
Once the wine starts to boil, add all the cleaned mussels and replace the lid.
After a minute or so, stir the mussels or shake the pot as the mussels at the bottom will open first.
Remove the lid and, with a pair of tongs, take out any mussels that are open and arrange them in a large serving dish. At this point you will need to move quickly as the mussels will all start to open at once and you do not want to overcook them.
If they all look as though they are open, just dump the whole lot into a strainer and then continue to arrange in the serving platter. Don’t serve any unopened mussels.
Once the mussels are arranged, cover liberally with the mango salsa and serve immediately, well, as soon as you have topped up the wine glasses, that is.
