Ingredients for Roast Lobster with Pink Butter Sauce (Langouste Rôtie au Beurre Rose Hostelleries Saint-Roch)
1 1/4–675g lobster
60g unsalted butter, melted
Kosher salt, freshly ground pepper
1/4 teaspoons herbes á tortue (or a pinch each of dried thyme, dried oregano, dried basil, and dried marjoram)
240ml pink butter, recipe follows
240ml dry red wine
2 tablespoons minced shallot
1/2 teaspoons dried thyme
1/2 bay leaf, crumbled
80ml double cream
240ml unsalted butter, cut into pieces
Freshly squeezed lemon juice, to taste
How to make Roast Lobster with Pink Butter Sauce (Langouste Rôtie au Beurre Rose Hostelleries Saint-Roch)
Into a large kettle of boiling salted water plunge the lobster and boil it, covered, for 2 minutes. Transfer the lobster with tongs to a buttered baking dish and with kitchen shears cut down the back of the shell without piercing the flesh.
Sprinkle the lobster with salt and pepper, brush it with the butter, and sprinkle it with the herbes à tortue.
Roast the lobster in a preheated moderately hot oven (191°C), basting it frequently with the pan juices, for 12 to 15 minutes, or until the flesh is firm.
Halve the lobster lengthwise, arrange it on a heated plate, and serve it with the butter sauce.
In a stainless steel or enameled saucepan combine the wine, the shallot, the thyme, the bay leaf, and salt and pepper to taste and reduce the wine over moderately high heat to about 2 tablespoons .
Add the cream and reduce the liquid by half. Whisk in the butter, 1 piece at a time, over low heat, adding each new piece before the previous one has melted completely. (The butter must not get hot enough to liquefy. The sauce should be the consistency of a light hollandaise.) Add the lemon juice and salt and pepper to taste and strain the sauce through a fine sieve into a heated serving bowl.
