These yummy snacks can be made up to two days ahead and kept in an airtight container. If the pastry has softened when you remove the twisters from the container, return them to an oven tray and heat in a moderately hot oven (190C) for about 5 minutes, or until crisp. Use oven gloves when taking the hot tray from the oven and place it on a wire rack until the twisters are cold.

1. Leave plastic film on pastry sheet and place it on a chopping board. Spread Vegemite on pastry with a plastic knife, leaving a 1cm border around edges.

2. Sprinkle cheese evenly over Vegemite. Fold one half of the pastry over the other to enclose the filling. Using a rolling pin, gently roll over the pastry to ‘stick' halves together. Peel off plastic wrap. Brush with egg yolk.

3. Cut pastry into 1cm-wide strips. Holding a strip at either end, twist in the opposite direction. Repeat with remaining strips. Place strips onto an oven tray lined with baking paper.

Under adult supervision, place oven tray in a hot oven (200C). Cook for about 15 minutes, or until golden and crisp. Remove from oven and cool on the tray before eating
