Heat the oven to 200°C/400°F. Unroll puff pastry on a floured surface and spread the chipotle paste over one half of the pastry. Spread the grated cheddar over the paste and then fold the sheet of puff pastry in half.
Roll the folded sheet of pastry out to ¼ inch thickness then slice into strips using a pizza cutter or knife. Line a baking sheet with greaseproof paper then hold both ends of each strip and twist several times before carefully laying on the baking sheet.
Once all of the strips have been twisted whisk the egg and brush each twist with the beaten egg. Place in the oven and cook for 12- 15 minutes checking occasionally to make sure they aren't burning.
