I have my experience in this area, and there were times when I did a pretty sloppy job cooking this one.
But ı can say I mastered spaghetti-frutti di mare after last monday. It was so successful that we overate! After a coffee, tea and smoking period, when we got back to our normal selves, we decided that it was the best spaghetti di mare, ever...
Ok, I exaggerated. But believe me, it was the best.
Here's the recipe:
You get frozen seafood, about 500gr.
Boil half box of barilla spaghetti no.5
As soon as pasta starts to boil you put in butter and olive oil together (as much as you like, but I find 1 tablespoon each to be just fine) into a large pan. As the butter melts, you add two cloves of garlic and let it infuse to hot oil for 30 secs. Then you add diced onions (1 big one would suffice) and cook for 2 mins. Then you add the seafood. You actually should put different kinds in a different order but I buy pre-cooked so I don't believe it will make any difference. You can add at this point half a glass of white wine and let it boil for a minute. Then you add about one glass of tomato pureé. Add salt and pepper, and maybe some paprika.
And then you wish for your spaghetti to be not overcooked and drain it and add it to the sauce pan.
I now wish to have had a picture of that dish but I will do it soon enough. But here's the seafood I always get.
