Squid sauce pasta

Generally my cooking is a bit conservative. It means I'm only cooking I succeeded to cook once normally. But to widen my repertory, I should challenge. :)
Today's challenge target is squid ("Ika"). Yeah, I love squid and have the experience to cook fried squid, seafood curry, and Sashimi. But I haven't cooked as pasta sauce yet. I've already eaten it at Italian restaurant, and it was very nice.
Because a squid has enough black ink is very expensive and off-season, I bought popular red squid.

1. Bake garlic, chili, and minced onion with butter.
2. Take viscera out from squid and strip skin.
3. Put cutted squid and its viscera.
4. Pour white wine and put salt, pepper and some herbs (if you have).
5. Put boiled tomato into it.

Well, this wasn't so bad, but I believe I should use more butter when I try again.
