Meanwhile, make cheese soufflés. Preheat oven to 180ºC (160ºC fan forced). Grease six ²/³ cup (160ml) metal dariole moulds or soufflé dishes, line bases with baking paper. Melt butter in a medium saucepan over medium heat, add flour, cook, stirring, 1 minute. Gradually stir in milk, stir until mixture boils and thickens. Transfer mixture to a medium heatproof bowl. Stir in ¾ cup of the cheddar, then egg yolks. Season to taste. Beat egg whites in a small bowl with an electric mixer until soft peaks form. Fold egg white into cheese mixture, in two batches. Spoon mixture into dishes. Place dishes in a small baking dish, add enough boiling water to the baking dish to come halfway up side of the dishes.

Bake soufflés 15 minutes or until firm. Cool soufflés 5 minutes, turn soufflés out onto a baking-paper-lined ovenproof dish. Cool. Spoon cream over soufflés, top with remaining cheddar. Bake a further 15 minutes or until puffed and browned.

Step 5

Place soufflés in serving bowls, pour soup around soufflés. Sprinkle with extra thyme.
