I cooked a fine lot of mussels tonight:
Preparation:
Wash mussels till water remains clear.
Check all mussels, and discard any with broken shells. If the shell is open by more than about .5 cm try to open it further. If it opens with reasonable force discard it. Remember, mussels are muscles that try to keep the shell closed. If you can open the shell by hand it is dead or nearly dead. Mussels should be cooked alive. Dead mussels are a health risk. Also, with every mussel, try to slide the two sides of the shell against each other to see if pops open. If it does, discard it. Remove any hairy growth using your hands or kitchen scissors.
All of this may seem a lot of work, but it isn't really. I worked my way through 2 KG of mussels in 10 minutes tonight. Having done the dirty work, let's get cooking:
Traditional recipes call for white wine. Don't waste your precious wine on cooking. I use sherry instead. It has a stronger taste (good for cooking), and it gets you an additional glass of wine to enjoy with the mussels. Pour sherry into pan. Add coarsely chopped onion, leek and carrot to the sherry. Fennel works well as well. A little garlic, and freshly ground pepper doesn't hurt either. Do add fresh thyme and rosemary. Both will happily grow in your back garden btw.
Cook the sherry/vegs/herbs mix for 5 minutes then add the mussels and cook for a further 10 minutes. Take the pan off the fire, shake well and rest for 5 minutes. Put pan back on fire and cook for a further 5 minutes. (This may seem a bit odd, but in my experience the mussels take on more flavour by precooking the veg and the resting).
Serve with warm french bread and whiskey sauce.
Whiskey sauce:
Take about 3 measures of ketchup to one measure of mayonnaise. Mix well.
Add chopped garlic and paprika powder to your liking.
Add a little whiskey, taste. Add more whiskey etc.
Now open that nice bottle of white wine, serve and enjoy
