Boil one litre of water and, once boiling, add the mussels. Within a few seconds, the mussel shells will start to open. Remove each opened mussel and set it aside. Discard any mussels that have not opened after a minute or so.
Drain mussels well. Open the mussel shells and remove the beards from the mussels.
Using one half of a shell, scoop out the mussel meat from the shell and set it aside. Retain twelve half shells to serve the mussels. Clean and wash these shells well.
to cook
Heat the pan over medium heat and add the oil. When hot, add the onions and sprinkle with the salt. Fry for eight minutes until the onions are soft and translucent but not coloured.
Add the green chilli and recheado masala, mix well and fry for two minutes.
Add the mussel meat and mix gently. Cover and cook for five minutes.
to serve
Remove mussels from heat. Place one mussel in a half shell and cover with a little of the gravy.
Garnish with coriander and serve.
notes
Make sure that the mussels that you buy are completely closed and not cracked or chipped.
This recipe specifies mussels removed from their shells, cooked, then served on half-shells. You could also cook them in the shells. If doing so, add 100ml of water after the masala and cook for another two minutes.
