In a large mixing bowl, mix together all the flours with salt.
Preheat the water to 45ºC (115 °F). Add 2 tsp of raw honey and stir. Add the yeast and let it work for 10 minutes. The yeast will bubble or create a foam. If it doesn’t, the temperature was not right, so you will have to start all over again.
Stir the psyllium powder into the yeast mixture. Let it rest for 2 minutes so it creates the gelatinous texture, then whisk it energetically
Add the yoghurt to the yeast mixture and stir well. Now, add the dry ingredients. Mix well with a wooden spoon. The dough will be sticky, but you will be able to work it with your hands greased with olive oil.
Cover the dough with a damp cloth and store it in a warm spot to rise for approximately one hour.
Preheat the oven to 200ºC (393 °F). Place a baking pan in the oven to preheat. Using some melted butter or olive oil, grease the dough with your hands and tap it in so that it "drinks" the fat. Place it in the preheated baking pan and bake for 40 minutes.
Reduce the heat to 100ºC and bake for another 20 minutes.
When the bread is baked, remove it from the oven and let it cool down. Try not to slice it before it cools down completely.
