Lobster bisque

Serves 6 Prep time 20 mins, cook 2 hrs 25mins John Gable tries to use local fresh produce, so Kangaroo Island lobster is his preference here.

For bisque, preheat oven to 200C, coarsely crush reserved lobster shells and combine in a roasting pan with prawn shells, vegetables, garlic, herbs and peppercorns. Combine butter and oil and brush over shells and vegetables. Season to taste with sea salt and freshly ground white pepper. Roast, stirring frequently, until fragrant and vegetables are tender and shells pink (30-40 minutes). Transfer to a large saucepan, add remaining ingredients except cayenne pepper, bring to the boil over medium heat, reduce heat to low and simmer until liquid is reduced by about half (1-1½ hours). Cool, then blend ingredients in batches in a blender until smooth and pass through a fine sieve. Season to taste with sea salt, freshly ground white pepper and cayenne pepper.

Meanwhile, for saffron mayonnaise, pound garlic and saffron in a mortar and pestle to a smooth paste. Transfer to a food processor, add yolks and 1 tbsp lemon juice and process to combine. With motor running, gradually add oil in a steady stream, blending until thick and smooth. Season to taste with cayenne pepper, freshly ground white pepper and sea salt. Makes 200ml (enough to cover lobster).

Melt 300gm butter without colouring in a saucepan over low heat. Bring to 70C, add lobster and cook, turning once, until opaque (10-15 minutes). Break into pieces. Keep warm.

Bring bisque to the boil, add remaining butter and cream, whisk to combine. Divide lobster among bowls, ladle over bisque and serve scattered with mche cress and toasted sourdough and saffron mayonnaise to the side.
