Pasta Al Nero Di Seppia
This stuff takes a lot of squid ink - 1 tablespoon/1 sachet per egg. Allegedly. And the rest!
I wanted to make a tagliatelli version for a dinner party but I couldn't find a single source of pre-packaged squid ink in the whole of Edinburgh, so I tried squeezing my own from a half-dozen squids. Unfortunately none of them had anything in their body sacs, and there just wasn't anything like enough ink in their heads so the result was disappointingly anaemic.
I just followed my usual fettuccine recipe.
Bear in mind that a 1 egg mixture goes a looooong way when it's just being served as a side dish.

I had a go at using just egg yolks rather than whole eggs, but it turns out you need at least some egg whites to hold the dough together. If you're making a large enough quantity you could just use one egg and then add egg yolks as necessary.
Three egg yolks, 5oz semolina and about ½ a white worked quite well instead of the proportions in the recipe below, and the taste may have been slightly richer.
May have been.

Ingredients
Method
Make a well in the semolina and beat in the egg, the squid ink and a little olive oil (this gets pretty messy - everything the ink touches turns black so expect a lot of cleaning).
Roll out the pasta, slice into tagliatellies or linguinies and hang over a clothes horse or similar until you're ready for them.
It's easier to handle them if they are a little dried out.
Cook for about 4 minutes in oiled water til al dente.
Lift out into a colander using spaghetti forks rather than pouring if you want to avoid the strands tangling up too much.
It really seems to take quite a bit of ink to get a nice black pasta - more than I had anyway.
This pasta also seems to be very stretchy, so when you hang it up to dry after you've cut it, make the lengths a bit shorter.

Second time around I had squid ink sachets, and this time the colour was terrific, the pasta no more stretchy than normal, but the flavour extremely subtle (though quite distinctive).
I doubt if it would get much stronger, even with the addition of more squid ink, though you could try: some recipes I've seen suggest a Tablespoon (3 teaspoons) of squid ink. Which is an awful lot more - good luck trying to wash that off your hands!
I imagine this would work best with a delicate creamy sauce, say shrimp with cream and garlic, or crabmeat with a light creamy tomato sauce. Or this?
I quite like the sound of this zucchini with saffron too.
