Clams

112

Clams (vongole in Italian) are a type of bivalve, extremely popular in Italian cuisine thanks to their intense but yet delicate flavour, and the fact that they require minimal manipulation and still provide fantastic results.

We have seen How to steam mussels , and the process for clams is very similar, what changes is essentially the way they need to be cleaned in order to get rid of all the sand and other impurities that you will find as they burrow under the sea floor.
Also, ask your fishmonger if they have already been purged (normally it is the case); if not, put them in a bowl filled with salty water and let them sit for several hours to expel all the grit and sand. Once that your clams have been purged, this is the process to follow:

  1. Put the clams in a large bowl and fill it with cold water
  2. Rub them between the palms of your hand as in the picture. Don’t be too gentle, you will need a bit of force:

  3. You will see that the water becomes cloudy:

  4. Change the water and repeat the operation several times until the water stays clear after rubbing the shells:
    108
    NOTE: some suggest to rub the shells with a stiff brush; that method works well with larger clams but the one I use works better for smaller ones, which are the ones I normally cook
  5. Discard all the broken shells and the ones that are not tightly closed
  6. Put them in a pan large enough to allow some extra room as the shells will open up and the overall volume will increase; add a splash of water (or white wine if you prefer). You can also add some crushed garlic if you like it.
  7. Cook on medium-high heat, with the lid on, for a few minutes, until they open up. NOTE: as usual with fish and seafood, overcooking is the most common mistake, so you should really pay attention and make sure that you take them off the heat as soon as they open up, otherwise they will shrink and will become tough and rubbery.
  8. Let them cool down with the lid on if not using immediately
  9. Discard all the shells that did not open up
  10. Using a colander lined with muslin cloth, strain the liquid released by the clams; you want to use it in your recipe as it’s packed with flavour.

Spaghetti ai Cannolicchi (Spaghetti with Razor Clams)

189

—————————————————————————————————–

INGREDIENTS (4 people)

360g spaghetti (or linguine)
12 razor clams
16 cherry tomatoes
3 anchovy fillets
100 ml dry white wine (optional)
1 tbsp. finely chopped onion
2 garlic cloves, minced
Finely chopped parsley
———————————————————————————————————-

Basic Techniques needed:
Razor Clams
How to cook pastaIf you are able to find razor clams (you will need to ask a real fishmonger, it’s not something you will find in a UK supermarket), this is a very quick and simply seafood pasta recipe that will not fail to impress your guests.

First, get organised:
Chop the onion (see How to chop an onion in Basics), mince the garlic and chop the parsley

When everything is ready, you can start cooking:

  1. Prepare the razor clams as below (see Razor Clams for details):
    Rinse them in running water
  2. Put them in a pan with a splash of water and cover
    Cook on medium heat for 2-3 minutes until the shells open up
    Once opened, discard the dark sac you will find in the middle of the clam
    Filter the liquid they have released as you will use it in your recipe
    Cut them in 1-inch pieces and then lengthwise
  3. Peel the tomatoes: prick their skin with the tip of a knife and plunge them into the bolilng water in the pot you will use for the pasta, then put them in a bowl filled with cold (better iced) water;
  4. Sweat the onion in 2 tbsp. olive oil for 4 minutes
  5. Add the garlic and the anchovy fillets and keep cooking on low heat
  6. When the anchovy fillets have dissolved into the oil, add the liquid from the clams and 100 ml water or white wine if using it;
  7. Peel the tomatoes, quarter them and add them to the sauce; cook on low heat
  8. When the liquid has reduced to 1/3, add the razor clams
  9. Cook the pasta in plenty of salty water (see How to cook pasta)
  10. Add the sauce to the cooked pasta, sprinkle with finely chopped parsley and serve
    TIP: instead of cooking the pasta completely, drain it a couple of minutes before the cooking time indicated on the packaging and finish it off with the sauce, adding a few tbsp. of its cooking water to prevent it form becoming too dry; the pasta will absorb all the flavours

Razor Clams

165

Razor clams owe their English name to their resemblance to the handle of an old fashioned straight razor, whilst they are called cannolicchi in Italian because their shape is also similar a small cane -canna in Italian (in fact, another name is bamboo clam).

Razor clams live in the sand in the seashore and, although not often commercially fished (mainly because they are quite difficult to catch due fact that they can burrow incredibly quickly in mud or sand soil), they are regarded as a delicacy.

Compared to other shellfish such as cockles and clams, or mussels, they have a sweeter, less salty and more delicate flavour, that makes them one of my favourites, something that I always buy when they are available

They are very simple to prepare too, are good both cold and warm, and can be the main ingredient of a quick and tasty pasta dish or a delicious salad.

See below how to prepare them:

  1. First, rinse them in running water
  2. Put them in a pan with a splash of water (I suggest you don’t use white wine as they will be ready very quickly and there would be no time to cook off the alcohol) and cover
  3. Cook on medium heat for 2-3 minutes until the shells open up
    175
  4. Once opened you will just need to discard the dark sac you will find in the middle of the clam (I assume it’s the stomach but I do not have any scientific knowledge to support this statementt), as it’s normally very gritty

  5. As usual with shellfish, filter the liquid they have released as it’s packed with flavour and you should use it in your recipe

Frutti di Mare (Seafood pasta sauce)

Basic techniques needed:

Tomato Sauce
And at least one of the following:

How to steam mussels
Prawns & prawn stock
———————————————————————————————

Ingredients (for 4 people):

1/2 onion, finely chopped
4 garlic cloves, minced
4 anchovy fillets
800g peeled tomatoes
Salt & sugar, to taste
Finely chopped parsley, to taste
Chilli pepper (optional but recommended)

600g of clams OR 600g of mussels OR 300g of each
6 large or 8 medium prawns
500g squid OR 500g cuttlefish

——————————————————————————————

Frutti di mare is the generic Italian word for seafood. Basically, we say ‘sea fruits’ instead of seafood.

However, meaning of the name aside, pasta with seafood is by far one of my favourites, as long as it is made properly and using good quality ingredients. In a nutshell, what I will describe here is a tomato sauce (see Tomato Sauce in Basics, you will just add some anchovy fillets when sweating the onions and squid or cuttlefish before adding the tomato) with the addition of various types of seafood, most of which will be cooked separately to get the best flavour and texture out of them, and then added to the sauce.

Also note that, since all the ingredients have to be fresh (although prawns and squid can be an exception, and I will explain it), and any reputable fishmonger that sells fresh fish will NOT have everything everyday, you will have to select the ingredients when doing your shopping. Therefore, I will provide guidance on different types of seafood but bear in mind that you don’t need to use them altogether, I would say that three works very well for me, I normally include squid or cuttlefish, that I cook with the sauce, some shellfish (either mussels or clams) and crustaceans (shrimps, but also langostines are good). If I find it fresh, I also love crab, as it gives a fantastic flavour. However, it needs to be treated after cooking or taken off the sauce and used separately as we will see.

NOTE: If you are using mussels, clams and/or prawns, prepare them before you start making the sauce, as you will need to use the liquid for your sauce:

How to steam mussels
Prawns & prawn stock

Also, the only items that you will cook with the sauce from the beginning are the squids (or cuttlefish if using). Shellfish needs to be cooked separately and added at the end, crustaceans (like prawns), once shelled, need to be added at the end as they required minimal cooking

This is the process. In order to understand this recipe, read it through to the end, as I will explain certain things at the end.

So. after you have cooked the clams or mussels and filtered their liquid, and made the prawns stock if using it do the following:

  • Sweat the onion for 5 minutes in 2 tbsp. of olive oil
  • Add the minced garlic and anchovy fillet
  • When the anchovy fillets have dissolved into the oil, add the squid (or cuttlefish), prepared as below (Next paragraph: How to treat seafood)
  • Cook gently without adding any liquid; the squid/ cuttlefish will release its own water, and cook on low heat until it has almost completely evaporated
    098
  • Add the tomato (blended and passed through a sieve – see Tomato Sauce)
  • Add some liquid:
    1) if using prawns, use the stock, made as described in Prawns & prawn stock
    2) if using mussels or clams, use the liquid, filtered as described in  How to steam mussels
    Even better if you use both!
  • Bring to the boil and then simmer, skimming the surface, for an hour or until the desired thickness is reached – if using crab, add it when the sauce is simmering -see below for cooking times
  • Season wilt salt and sugar
  • Add the other ingredients: prawns, shellfish or whatever you like (see below for cooking times)
  • Add a good handful of finely chopped parsley and some chilli pepper (optional but recommended)
  • Let it cool down completely before using it.

HOW TO TREAT SEAFOOD:

 

Squid and cuttlefish will make your sauce more substantial and will also add interesting note to your dish. Since I like to be in control of the outcome when I cook, I prefer to cook them separately and add them to the sauce at the end, when the sauce is ready; cooking them in the sauce you might end up overcooking them

SQUID
First, some consideration on the product: make sure you buy unprocessed squid . Squid can be fresh or defrosted, it will still be good, but do not buy any precooked one; also, be wary of the so-called calamari (which indicates squid rings in English but is simply the plural for squid in Italian), as it might be processed as well and go for the whole squid; if unsure on how to clean it, have your fishmonger do it for you.
Once cleaned, lay the squid tube on the cutting board and you will find a groove inside; with a very sharp knife, cut along that to open the tube up. You will see that the two sides do not have the same consistency, the outside is harder and the inside is softer
You can cut it in small pieces now, otherwise, you can give it a Chinese style criss-cross pattern that will make it look better when cooked: using a very sharp knife and being light-handed, make shallow incisions; it is preferable to do this on the softer side; whilst it is preferable to cut it into pieces with the harder side up.

  • Once that has been cut, season with salt and cook gently in a tbsp. of oil without adding any liquid; the squid/ cuttlefish will release its own water, and cook on low heat until it has almost completely evaporated
  • 098
  • At that point, try if itstender enough; if not, add a splash of liquid (water or white wine, depending on your taste) and cook until the desired texture is reached (you might need to repeat the operation)

CUTTLEFISH: to some extent it is similar to squid once cooked, although much different as it’s got a big bone and the body is not a tube like squid; it’s also got a much bigger ink sac (the ink can be used as an ingredient in many other preparations) and it is more tender and requires a shorter cooking time compared to squid.
Other than that, what I said about the criss-cross pattern applies to it as well

MUSSELS: either mussels or clams is a must in a seafood sauce, it won’t just look and taste right without. Mussels are very delicate and the long cooking time of the sauce would destroy them; furthermore, the liquid that they release needs to be filtered, as it might contain sand and other impurities, therefore you should cook them separately.
See How to steam mussels for more details. I suggest that you cook the mussels and filter their liquid before adding the tomato sauce to the squid (or cuttlefish base). At this point you should know that you need to add some liquid to the tomato in order to simmer your sauce, and you can add that liquid instead of /along with the water.
IMPORTANT: the liquid is very salty, so that will reduce the amount of salt you need to add to the sauce
Cooking time in the sauce: add them to the sauce after turning the heat off as the  mussels should be completely cooked already and overcooking will ruin them

CLAMS: clams are cooked pretty much like mussels, the only difference is that they do not have bits of seaweed coming out of the shell but will need to be rinsed thoroughly before cooking. Everything else is the same, including filtering the liquid and adding it to the sauce
Cooking time in the sauce: you can add them after turning the heat off as the  clams should be completely cooked (same as mussels)

PRAWNS
See: Prawns & prawn stock :
Shells and de-vein the prawns, make a stock with the heads and shells, add it to the tomato sauce and simmer until it reaches the desired thickness.
You can cut the tails as you wish: in small pieces, or lengthwise (they will take a nice spiral shape when they cook), or just leave them whole and place one on top of the pasta for a nice presentation
Cooking time in the sauce: prawn tails require minimal cooking, 3-4 minutes is enough

CRAB
I do not suggest a whole crab for your sauce, unless you’ve got a massive pot. Also, use fresh crab (it should actually be still alive when you buy it). If only precooked crab is available, just leave it, it’s pointless.
To make it easier I suggest that you buy the claws only (obviously is available and fresh): cook them in the sauce until you smell the crab (you won’t miss it it’s a very distinctive aroma), then take them off the sauce, rinse and break the shells to extract the pulp. The pulp can then be added to the sauce, but personally I prefer using it for other preparations (a filling for ravioli, a mousse, a fish cake just to name the most obvious)
