In a jug, add the warm water, yeast, granulated sugar and a teaspoon of flour.
Give it a stir, and set aside for 10 minutes until the yeast is all foamy and bubbly.
In a large bowl, sift the flour, add the canned pumpkin, yeast mixture, milk, melted butter, light brown sugar and salt, and knead well into a dough that does not stick to the hands.
Cover the bowl with clingfilm and leave to proof in a warm place for at least an hour until the dough doubles its volume.
Divide the dough into 8 balls, then roll each ball into a rope, then shape into a lose knot (see photos).
Beat the egg, and brush each roll with it, then sprinkle sesame seeds and caraway seeds over (optional).
Bake in the pre-heated oven at 180 degrees Celsius (350 Fahrenheit) for 20 minutes.
