These are Indian shortbread cookies called nankhatai. A nankhatai is a simple eggless cookie with butter, flour, and sugar as the main ingredients. Some spice is added to give the cookies an extra zing. I used a mixture of besan (chickpea flour), all-purpose flour, and semolina as the base. Black pepper adds warmth to these sweet, buttery cookies and a little bit of fruity jam or almond on top gives these thumbprint cookies their last finishing touch. You can use any kind of nut or jam of choice.
