Combine all-purpose flour, salt, wheat flour, semolina, chickpea flour (besan), eliachi powder, and powdered sugar in a large mixing bowl.
Mix until all the ingredients are well blended.
Add ghee.
With your fingers, work the ghee into the flour mix.
Mix until the mixture becomes crumbly.
Add melted ghee to this flour mix and mix until it forms a soft, pliable dough. Add ghee one spoonful at a time, as you may not need the recommended quantity. Tip — When you add melted ghee, the nankhatai dough will be extremely smooth and soft but not sticky. Take some dough in your hand, and roll it between your palms to finish rounding it like a ball. Form a crack-free, smooth round ball.
Flatten the ball slightly in the palm of your hand and use your fingertips to smooth out the edges of your nankhatai.
Repeat this process until all the dough is shaped.
Place them on a baking tray.
Gently make a small cut on top of each nankhatai.Tip — This indent or cross on top will ensure that the nankhatais have room to expand and will develop beautiful cracks during baking. Sprinkle eliachi powder. Cover and chill the unbaked nankhatai in the refrigerator for 30 minutes to an hour. Tip — This is an important step, and it will prevent over-spreading. When these chilled cookies are baked, the solidified fat/ghee takes time to melt, and during baking, whatever the steam is released, it puffs up the dough, and the cookie spreads out less and becomes flaky. And if we start baking the dough without chilling, the fat (ghee) will melt immediately, resulting in flat-out, greasy cookies. Preheat the oven to 350°F. After the desired time is over, bake the chilled nankhatai in a preheated oven for 14-16 minutes.
Once the cooking time is done, remove the nankhatai from the oven.
The center of nankhatai will still be very pale and soft when fresh out of the oven. This is important - let them cool slightly in the tray for 4-5 minutes. As they cool, the nankhatai will continue to firm up.
Here is what the nankhatai should look like right as they cool.
Garnish with slivered nuts and store it in an airtight container at room temperature.
