Try this delicious recipe I recently found....serves four.
A dab of cooking-oil
110g caster sugar
165g coarsely chopped rhubarb
1 tbsp water
1 tbsp icing sugar
Preheat oven to 200°C (180°C fan)
Glaze four 250ml ovenproof dishes with tiny bit of cooking-oil (I rubbed on with kitchen towel dapped in oil). Sprinkle base and sides of dishes with 2 tablespoons of the caster sugar. Stand dishes on oven tray.
Combine rhubarb, water and 2 tablespoons of caster sugar. Cook, stirring, over medium heat, about 10 minutes or until mixture thickens. Transfer mixture to medium heatproof bowl.
Meanwhile, beat egg-whites in small bowl with an electric mixer until soft peaks form. Gradually add remaining caster sugar; beat until firm peaks form.
Fold egg-white mixture into warm rhubarb mixture, in two batches. Spoon mixture into dishes. Bake in oven about 12 minutes.
Serve souffles immediately, dusted with sifted icing sugar.
