The Guardian has some really nice squid recipes on their website.
Preparing and cooking squid is easier than most fish. The only thing to remember is not to cook it for too long. If grilling, the pan must be extra-hot so the squid cooks in only a minute or two. Otherwise, it goes tough.
If you have read the blog, you will know that I am a fan of squid. There are three very nice recipes in the article.
