Now let's see how to make these cheese and onion pasties; preheat your oven to 200°C/180°C/Gas Mark 6. Line a baking tray with baking parchment and set aside.

Pop your butter and onions in a pan over a medium heat and cook for about 5 minutes until the onions have softened. Leave in the pan to cool slightly.

Meanwhile roll out your block of pasty to about about ½ cm thickness. Cut the pastry into 6inch circles, you can you the base of a cake tin as a guide to cut around. Lay the circles of pastry on the prepared tray.

In a bowl mix together the grated cheese, onions, pepper and chives. Place a dollop of the mixture in the centre of each circle of pasty – be careful not to over fill the pasties as the mixture will spill out as it bakes. 

Fold each circle in half and crimp the edges together to create a pasty shape – you can use a fork to help create the crimped edges.

Brush the top and sides of each pasty with your beaten egg to glaze. Pop in the oven and bake for 25-30 minutes until the pastry in golden brown.

Your cheese and onion pasties are best enjoyed warm!
