In a large mixing bowl, combine the ragi flour, oats flour, flaxseed powder, psyllium husk, baking powder, baking soda, and salt. Mix thoroughly to ensure all ingredients are evenly distributed.
Add the olive oil and warm water to the dry ingredients. Stir well until everything is combined.
Add the vinegar and mix again. The mixture will begin to thicken almost immediately as the psyllium husk absorbs water and forms a gel-like structure.
Once the mixture becomes thick and evenly combined, transfer it to a greased or lined bread mold. Smooth the top using a spatula.
Allow the loaf to rest on the kitchen counter for 10 minutes. This short resting period helps the psyllium husk hydrate fully and improves the final texture of the bread.
Bake in a preheated oven at 180°C (356°F) for 70–80 minutes or until the loaf is firm and cooked through.
Remove the bread from the oven and allow it to cool completely before slicing. This step is important because the bread continues to set as it cools.
