Method

1) To make the shellfish butter, preheat the oven to 200°C (180°C fan-forced). Place the shellfish shells, onion, garlic and oil in a medium deep-sided roasting pan. Place in oven and cook for 20 minutes, or until golden brown. Reduce the heat to 120°C (100°C fan-forced), add the melted butter and cook for a further hour, or until the garlic is tender. Remove the soft garlic cloves and set aside. Strain the shellfish mixture through a fine-mesh sieve, reserve the butter and allow to cool.

2) Place the fish stock in a large saucepan and bring to the boil. Add the marron and poach for 4 minutes. Remove the marron from the stock and refresh in ice-cold water. Set the stock aside.

3) Using a sharp knife, split the marron lengthways and remove the coral (the orange membranes) from the head section. Set the marron aside, reserving the coral.

4) To make the thermidor sauce, crush the soft garlic cloves with a fork. Place half the shellfish butter, eschalot and garlic cloves in a large frying pan over medium heat and cook for 1 minute, stirring, or until eschalot is tender. Add the flour and cook, stirring, for 1-2 minutes. Gradually add 400ml of the reserved fish stock, stirring until the mixture is thickened and coats the back of a spoon. Add the reserved coral, gruyere cheese, chervil, chives and pepper, stirring until well combined. Remove from the heat and set aside to cool slightly.

5) Pre-heat the grill to high. Place the halved marron on a baking tray lined with foil and spoon over the thermidor sauce. Cook for 8 minutes or until the sauce is golden. If you wish, cover the marron (especially the claw) with foil to prevent burning.

6) Place the marron on a serving plate and lightly dust with the bush tomato powder.

Chef’s Note

Bush tomato powder is available from specialty stores. Leftover shellfish butter can be frozen for up to 2 months.
