There is one drawback - sorry there's no delicate way of stating this - it makes your wee smelly. It's very strange and very pungent and apparently it doesn't happen to everyone .
Last night we had coq au vin blanc, a Nigel Slater recipe - it's basically browned chicken thighs, lardons of smokey bacon, onion, garlic, thyme and chestnut mushrooms - I forgot to buy the mushrooms, silly woman - white wine and cream. It's a really unctuous dish. We had it with some Jersey Royals, carrots and of course the noble spears.
The asparagus makes a great 'dipper' for leftover sauce !
