Contrary to popular belief they are not difficult to make at all and can be made at home for a fraction of the price super markets / bakery's charge.
What you will need:
1 packet puff pastry - I used a 500g block of Jus-rol puff pastry which cost £1at the supermarket. This was sufficient to make 16 cheese myoms.
1 egg - used to glaze
Some cheese - does not need to be anything fancy, I used the cheapest supermarket own brand of basic cheddar. You can use as much or as little as you like.
Some black pepper - Again you can use as much or as little as you like.
Plain flour - just a small amount used when rolling out the pastry.
Baking tray - any flat metal tin which is oven safe will do.
Greaseproof / baking paper - needs to be enough to cover your tray / tin
A bowl to beat your egg in and a knife to cut the pastry.
Ok lets get started.....
Step 1: Roll out the pastry, coat with beaten egg, cheese and black pepper
Sprinkle some plain flour on to the counter. Get your pastry block out of the fridge and roll it out. If you don't have a rolling pin you can use a glass / plastic bottle to do this, just make sure its clean :)
Beat your egg in a bowl and brush over the rolled out pastry. If you dont have brush, you can use clean fingers to apply the egg.
Then grate cheese all over the pastry and add some black pepper ontop of the cheese.
You should end up with something similar to the picture, however my picture was taken before I added the black pepper.
