In a container, combine water, yeast, salt, oil, and sugar.
Add flour, stir briefly to moisten with a wooden spoon. Add pumpkin seeds and flax seeds. Stir until evenly combined and no dry flour remains.
Knead in the bowl for around 5 minutes. You don't need to knead as much as normal dough.
Cover with a loose lid. Let rise to double in volume in a warm area.
Divide the dough into 3 balls. Shape the bread by stretching and tucking the dough.
Place each loaf into a container or banneton. Cover with plastic, leaving enough space for the rising of the dough. I use a plastic grocery store bag.
Refrigerate overnight, or store the dough in the fridge for up to two weeks.
Preheat oven to 230 c and place a cast iron pot in the oven. Pot must have a lid. I use a tagine.
While your oven preheats, wet your dough by brushing or misting with water. Sprinkle on pumpkin seeds and flax seeds, and top by sifting some flour through a mesh sieve. Score with a pattern of choice with a sharp knife, making cuts 1-2 cm deep.
Bake for 20 minutes, remove the lid, and bake for an additional 20 minutes.
