Step 1

Place the lamb fat in a frypan over medium-low heat. Add the cabbage, onion, celery, carrot, and green beans. Season with salt and cook for 8 minutes or until vegetables are soft but not coloured. Add the curry powder, crumble in the stock cube and stir to combine. Add the mince, breaking the meat apart with a spatula, and cook for a further 5 minutes or until browned. Add the cooked barley, stir to combine and set aside.

Step 2

Place the butter in a small saucepan over medium heat. Once melted, add the flour and whisk to combine. Cook for 2-3 minutes, then add 150ml water and whisk until thick and combined. Remove from the heat and add the cabbage mixture. Combine well, transfer to a bowl and place in the fridge to chill the completely.

Step 3

For the pastry, place the flour, egg, 1/2 cup (125ml) water and 1 tsp salt into the bowl of a stand mixer with the dough hook and knead on low for 10 minutes or until smooth. Cover dough with a clean cloth and rest in the fridge for at least 30 minutes or until needed.

Step 4

Divide the dough into four pieces and place on a floured surface. Roll one piece of dough until very thin and about 19cm wide and 19cm long, adding extra flour to ensure that the pastry does not stick.

Step 5

Using your hands, shape 1/4 of the cooled filling mixture into a log and place along one edge of the rolled dough, leaving a 1.5cm border. Brush the pastry all over with oil, then roll tightly, ensuring there are no gaps or bubbles and stretching out the dough as you go, until you reach halfway. Fold over the ends of the pastry, trimming if necessary, then continue to roll until all edges are sealed. Use a clean brush to press over the pastry to create a dotted effect. Repeat with remaining dough and filling mixture. Chill for 15 minutes.

Step 6

Half-fill a saucepan with oil and heat to 180°C on a kitchen thermometer. Working with one roll at a time, fry for 5 minutes or until golden and crisp all over. Remove from the oil and drain on a wire rack set above a baking tray. Repeat with remaining rolls. Serve immediately.
