One of my favourites is:
40 mussels
100ml white wine
100ml stock (chicken oxo cube is fine)
1 finely chopped onion
3 cloves garlic chopped
300ml cream
2 tsp chopped fresh thyme
2 Tbsp chopped Parsley
2 tsp grated fresh Ginger
2 Spring Onions
freshly ground black pepper for seasoning
100g butter - should be unsalted but don't usually have it, so normal stuff is fine.
Wash and de-whisker mussels, put them in a large pot with the wine, stock, onions and garlic.
Cover with tight fitting lid and bring to the boil rapidly.
Shake the pot at times to move the mussels around.
When they start to open remove them and put them in a large bowl and cover to stop them drying out.
Boil the stock to reduce slightly and then add the cream and herbs.
The recipe says to reduce this further by half, but we are usually too impatient, so we let it boil for a wee while then remove it from the heat and add the butter and season and give it a whisk with a fork.
You can either divide the mussels up into serving bowls and ladle the sauce over, or just chuck it over the big bowl and fight over them.
Serve with crusty bread to mop up the sauce.
