In a bowl whisk together yeast, sugar, buckwheat, corn starch, brown rice flour, and salt.
In a separate small bowl mix together psyllium husk and 1 cup of warm water. Continue to stir until a gel like mixture forms.. how cool is that? Add the gel to the dry ingredients.
Next up pour 1 1/2 cups warm water, olive oil, and 2 tsp of apple cider vinegar into the dry ingredients. Using a spatula mix the dough. At first it will seem more like a paste than a dough, trust the process here. Continue to stir the mixture for about 5-10 minutes until the dough easily comes off the sides of the bowl.
Now heavily flour your working surface with buckwheat flour and plop the dough out on to the counter. Flour your hands and start kneading the dough over itself on the counter. The dough may feel very sticky and that is ok. Add additional flour as needed. Dough should be sticky, but shouldn't stick to your hands while kneading. Work dough into a ball shape. You are doing great!
Next up pour pumpkin and sunflower seeds onto the counter top and drop the top smooth side of the dough ball on top of them. Flip dough over and place on a parchment paper lined baking try. Cover dough with a clean tea towel and let the dough rise for 60-90 minutes or until it has doubled in size.
After the dough has been rising for about 40 minutes, preheat the oven to 450F. Place a cast iron pan (or any pan that absorbs heat) into the oven. Once dough is done rising place a baking sheet or pan into the bottom rack of the oven and fill with water. This creates a humid, steamy environment which helps the bread rise.
Once dough has doubled in size, remove tea towel, and with a sharp knife create small slits on top of the bread loaf. Now, VERY CAREFULLY remove hot cast iron pan from oven and place the parchment paper and dough onto the pan. Place pan into the humid oven and bake for 30 minutes.
After 30 minutes of baking remove the water pan at the bottom of the oven and bake the loaf for another 30 minutes or until it is nice and browned.
Let loaf cool for 10 minutes and then slice and enjoy!
