Mix Dry Ingredients: In a large bowl, whisk together the 400g fine semolina, salt, and baking powder until well combined.
The "Sandy" Texture (Sandage): Pour in the 50ml vegetable oil. Use your hands to thoroughly rub the oil into the semolina grains. Keep mixing until the texture looks like wet sand and every grain is coated. This step is the secret to the crumbly texture.
Add the Water: Gradually pour in the 300ml lukewarm water while mixing gently with your fingers to distribute it.Important: The dough will be very soft and quite sticky (almost like a thick batter). Do not knead it! Just mix until combined. Mama's Cold Pan Method: Take your cold non-stick pan (do not put it on the stove yet).- Rub the 1 tbsp soft butter all over the bottom and sides.- Sprinkle a generous layer of extra dry semolina over the butter (this creates the golden crust). Shape the Dough: Pour the soft dough directly into the cold, prepared pan. Lightly dust your hand with semolina and press the dough down flat until it forms a perfect circle (about 1.5 cm thick). Smooth out the edges and sprinkle the top with more semolina.
Cook: Place the pan on the stove over Medium heat. Cook for about 7 to 10 minutes. You will know it is ready to flip when the edges look golden and the top feels dry to the touch.
Flip & Finish: Use a plate or a flat lid to carefully flip the Harcha. Slide it back into the pan and cook the other side for another 3-5 minutes until golden brown.
