Indian Spiced Mushroom Sauce

Cultivated mushrooms are greatly improved by spices, and this creamy sauce transforms roast and grilled chicken or lamb. It is quite piquant despite the cream. Serve the sauce with pasta dishes. Alternatively, you can make a delicious egg curry by slicing hard-boiled eggs and mixing them in with the sauce. The meatier chestnut mushrooms are ideal for this sauce if available.
