Fresh Mushrooms in Shrimp Roe Sauce

Fresh straw mushrooms found in the market in Hong Kong are a treat. Although they are not available in the West, I found this dish tastes almost as good made with fresh domestic mushrooms. The technique is to blanch the mushrooms quickly; they absorb moisture that they later give up as they cook. The shrimp roe gives this dish a distinctive flavour, but you can substitute shrimp paste if shrimp roe is not available.
