Wash the pumpkin, roughly cut it into pieces and grate it. Dissolve honey, yeast and sugar in lukewarm water and add it to the pumpkin. Add flour as well and knead the dough for about 1 minute.
Add salt and seeds and knead the dough very well for about 10 minutes. Shape into a ball and put it back into the bowl. Cover with cling foil or beeswax wrap and let the dough rest at room temperature for about 4 hours, carefully folding it after about 2 hours.
Divide the dough into 8 pieces and shape them into bread rolls. You can use a kitchen string to "wrap" the buns as if you wrapped a present to give them the pumpkin shape. Preheat the oven to 230 °C with the pizza stone or a baking tray in it. Put a bowl of water in your oven or use the steam function of the oven if you have one.
Bake the pumpkin bread rolls on the hot pizza stone or baking tray for about 15 minutes.
