Pasta in mushroom sauce

I adapted this recipe from a similar one I made a couple of months back, and the medley of mushrooms, creamy sauce, basil and chilli flakes was as good as I'd hoped it would be. I tossed in a few chicken sausages for the hubby and kids, but thought it was really good without any of it.

200 gms macaroni (or any other pasta)

1 packet mushrooms
1 onion chopped fine
6-8 pods garlic
1 cup milk
2 tbsp cornflour powder
1 tbsp chilli flakes
3 tbsp basil, shredded
1 tbsp butter
Salt to taste

Method:
Cook the pasta in sufficient water (and 1 tsp salt), stirring constantly to ensure it doesn't stick. Drain and keep aside. Reserve some of the water that the pasta was cooked in.
Heat the butter, Saute garlic (peeled and cut lengthwise), and onions till transparent.
Wash the mushrooms. Chop lenthwise in half. Add mushrooms to onions and garlic, and saute till browned.
Sprinkle the cornflour, salt and chilli flakes and stir till well coated. Once browned, add milk gradually, with constant stirring.
Let the milk simmer for a few minutes till thickened.
Stir in the basil (reserving a little for garnish) and turn off the flame.
Add pasta and mix well (add the reserved pasta water, if required).
Check for salt and serve, garnished with fresh basil leaves.
