I decided to use my bread maker to make the dough, and then just had to roll it out, fill, roll it up, cut and give it a second rise. It worked out really well, and I'm very happy with the result.
You can, of course, make the dough by hand.
The recipe said it made 12, but I made one too big so only got 11!
2 tspns instant yeast [I used 1 sachet and it worked fine]
150ml milk which has been scalded and cooled
1/2 tspn salt
1 heaped tspn freshly ground cardamom
325g strong white flour
60g soft butter
60g caster sugar
3 tspns ground cinnamon
Beat the egg and divide in half - half for dough and half to glaze buns.
Bread machine - put all the ingredients into the bucket and run on dough cycle.
By Hand - put flour and butter in a bowl and rub in; fold in the salt, sugar, cardamom and yeast. In another bowl pour in the milk and add half the egg and mix together. Add to the dry ingredients. Mix with your hand till you get a smooth, stretchy dough [takes about 5 mins]. Leave the dough in a warm place till doubled in size. Knock back and knead again for 2-3 mins.
For both methods:
Once the dough is ready, turn onto a floured surface and roll into a large rectangle about 1/2 cm thick.
Make the filling - beat the butter, sugar and cinnamon together till smooth.
Spread the filling over the dough and roll up like a swiss roll. Cut into 12 slices.
Put each slice, cut side up, in a muffin case on a baking sheet. Cover with a damp teatowel or clingfilm and leave for about an hour to double in size.
Heat oven to 210C/gas 6-7 . I used gas 7 and a few buns were overcooked.
Egg wash the buns with the other half of the egg, and sprinkle with pearl sugar.
Bake buns for about 6 mins till golden.
Here's my buns before the second rise.
And here's a ready-to-eat bun.
They are delicious, and would be lovely warm for breakfast. For my own tastes, as a cinnamon fanatic, I'd like a bit more filling, otherwise I wouldn't change anything. I thought it would be a really complicated recipe to make, but it's easy, tho' a bit time consuming if you're making your own dough. I brought some pearl sugar back from France, but I'm sure one of the supermarkets would have some. The cardamom just gives a hint of another flavour in the background. I'll certainly make these again.
