In a large mixing bowl, whisk together the flour, sugar, and salt until evenly distributed. This ensures that the sweetness and saltiness will be consistent throughout the cookies.

Cut the cold butter into small cubes. Add the butter cubes and tahini to the flour mixture. Using your fingertips or a pastry cutter, work the ingredients together until they form a cohesive dough. The texture should be smooth but not sticky - similar to shortbread dough. If it feels too dry, add a teaspoon of water; if too sticky, a little more flour.

Divide the dough in half and roll each portion into a log about 8 inches (20cm) long and 1.5 inches (4cm) in diameter. Pour the sesame seeds onto a flat plate or baking sheet. Roll each log in the sesame seeds, pressing gently so they adhere to the surface. Wrap each log tightly in plastic wrap or parchment paper.

Refrigerate the wrapped dough logs for at least 60 minutes until firm. This step is crucial for the cookies to hold their shape during baking. Preheat your oven to 350°F (180°C) and line two baking sheets with parchment paper. Unwrap the chilled dough and slice into rounds about 1/3-inch (8mm) thick. Slightly flatten each cookie with your palm or the bottom of a glass. Arrange on the prepared baking sheets leaving about 1 inch between cookies. Bake for 12-14 minutes until the edges are golden brown and the sesame seeds are lightly toasted.
