In a large bowl,
stir together the milk, butter, sugar and yeast.
Leave for 15 minutes to dissolve. Stir in the egg
yolk, salt and 275g/100z/2 1/2 cups of the flour. Add
half the remaining flour and stir to obtain a soft
dough.
Transfer to a
floured surface and knead, adding flour if
necessary, until smooth and elastic. Place in a
bowl, cover and leave in a warm place until the
dough doubles in volume, about 1 1/2-2 hours.
Grease a baking
sheet. Punch down the dough with your fist and cut
into 12 pieces the size of golf balls. Roll each
piece into a rope, twist to form a knot and place
2.5cm/1in apart on the sheet. Cover loosely and
leave to rise in a warm place
until doubled in
volume, about 1-1 1/2 hours.
Preheat the oven
to 180C/350F/Gas 4. Brush the knots with the egg
glaze and sprinkle over the poppy seeds. Bake until
the tops are lightly browned, about 30 minutes. Cool
slightly on a wire rack before serving.
