1. Lightly grease an 18cm wide x 8cm deep (6 cups)
souffle dish suitable for the microwave.
2. Combine flour and caster sugar in a bowl. Whisk together melted butter, orange juice, marmalade and egg. Stir into flour mixture until well combined. Pour into prepared dish.
3. To make the sauce, place orange and lemon juices in a microwave-proof jug. Stir in caster sugar. Cook for 2 minutes, stir well, then continue cooking until boiling. Carefully pour over the back of a spoon on to pudding, ensuring it is evenly covered.
4. Place a rack or upturned dinner plate in microwave. Place pudding on top.
5. Microwave on high (100 per cent) for 6 minutes, until a skewer inserted at edge of pudding comes out clean. The centre should still be sticky. Cover and stand for a few minutes before serving.
