Pasta in Cream Sauce

This was my 1st try at Cream-based Pasta sauce.
Fingers crossed ;)

With a vague impression of the cooking process, i was off to the Supermart for my Milk & Butter purchase.

In brief, the steps as followed:

1. Heat oil, add chopped Onions, Garlic to pot (let it cook)
2. Add in a ladle of Pasta cooking water, then the Prawn Heads, Ham bits and Mushroom.
3. Milk in, followed by Butter (Stir till dissolve)
4. Sprinkle Pepper as seasoning
5. Pour in the Cooked Pasta.

Mama Mia! Ric gave me a passing score :)
But i've been reading up recipes and endeavor to do better.
