Croissage rolls

Method

1. Heat oven to 200°C/180°C fan/gas 6. In a large bowl, combine the sausagemeat, cheese, onion, apple, chutney and herbs, and season with a little salt and pepper (sausagemeat can be well seasoned already). Fry a little of the mixture in a non-stick pan first, then taste to check the seasoning and the flavours.
2. Roll into 4 sausages, compacting the sausagemeat so it sticks together, then put on the prepared baking sheets and bake for 5 minutes. Remove and leave the sausagemeat to cool completely.
3. Meanwhile make the dough. Mix the flour, sugar, yeast and salt in a mixing bowl, then grate in the frozen butter. Use your fingertips to gently coat the butter strands in flour.
4. Add most of the water and mix gently with a round-bladed table knife to form a soft but not sticky dough, trying not to crush the butter too much. Add more water if needed.
5. Lightly dust the dough and a clean work surface with flour. Roll out the dough to a long, thin rectangle, roughly 20cm x 60cm. It will look quite rough initially but bear with it.
6. With the short edge facing you, fold the bottom edge two thirds of the way up and over the dough, then fold the third furthest away from you over this, to give 3 layers of dough. Rotate the dough 90 degrees. This is one ‘turn’ (see tips).
7.  Roll out, then fold in the same way as above twice more, rotating 90 degrees after each folding, making 3 turns in total. Chill the dough for at least 30 minutes before rolling and filling (see Make Ahead).
8. Roll out the dough to a rectangle just over 60cm x 24cm, trimming the edges for neatness if necessary. Cut the dough in half lengthways using a sharp knife, so you have 2 rectangles, roughly 60cm x 12cm.
9. Spread the mustard over each piece of dough, then arrange 2 of the cooled sausagemeat logs down the centre of each piece of dough (squidge the meat together to join the two up). Don’t worry if the sausage breaks up a little. Brush the edges of the pastry with a little beaten egg and roll it over to encase the meat, then pinch gently along the seam to seal. The seal can be left underneath, on the side or on top.
10. Cut into 4cm long pieces (or whatever size you prefer). Transfer to the baking sheets lined with clean non-stick baking paper, then cover loosely with lightly oiled cling film. Leave at room temperature to rise until the dough is puffy and almost doubled in size (this can take up to a couple of hours, depending on the temperature; see tips).
11. Heat the oven to 210°C/190°C fan/ gas 6½. Brush the tops of the sausage rolls with more beaten egg, then bake for 15-20 minutes until golden brown, turning down the temperature to 190°C/170°C fan/gas 5 after 10 minutes if they look as if they’re browning very quickly. Serve the croissage rolls warm or cold, with extra mustard, chutney and/or pickles alongside.
