SERVES 4

6 tbsp vegetable oil
5 tbsp plain flour
2 large onions, peeled and chopped
4 celery sticks, trimmed and chopped
2 red peppers, cored, deseeded and chopped
4 garlic cloves, peeled and chopped
225g chorizo (or andouille) sausage, sliced
800ml fish or chicken stock
400g white crabmeat (or cooked crab claws)
6-7 spring onions, trimmed and chopped
pinch of cayenne pepper
sea salt and black pepper
12 live oysters
handful of flat-leaf parsley, chopped

Heat the oil in a large, wide pan over a medium-high heat. Sprinkle in the flour and cook, stirring, until the mixture turns golden brown (forming a brown roux).

Tip in the onions, celery, red peppers and garlic.

Cook, stirring frequently, for about 8-10 minutes or until the vegetables are soft. Add the chorizo and cook for another 2-3 minutes.

Gradually add the stock to the pan, a ladleful at a time, stirring continuously. Let the mixture simmer, stirring often, for about 30 minutes until the stock is thick and flavourful, and the vegetables are soft.

Add the crabmeat, spring onions, cayenne and salt and pepper to the pan and stir well. Finally, shuck the oysters and tip them into the pan, along with their strained juices. Simmer for a couple of minutes, then turn off the heat.

Ladle the gumbo into warm bowls and scatter over the chopped parsley. Serve at once, with plain rice.
