Position the rack in the middle of the oven and preheat to 350°F. Line a large rimmed baking sheet with parchment paper.
Using a fine grater, zest the orange until you have 1 teaspoon of zest. Squeeze ⅓ cup of juice from the orange into a large bowl. Reserve the rest of the fruit for another use.
To the bowl, add the oil, sugar, brandy & zest, & whisk until the sugar is dissolved.
In a medium bowl, whisk together the flour, baking powder, cinnamon, cloves & baking soda. Add the dry ingredients to the wet ones in several batches, stirring at first with a spoon or spatula to incorporate. When the dough becomes difficult to stir with the last additions of dry ingredients, use your hands to knead the dough to incorporate.
Cover the bowl & let the dough rest for 10 minutes.
Spread the sesame seeds on a wide plate. Roll the dough into 1½" balls. Roll each ball in the sesame seeds, pressing a bit with your fingers so that they adhere, then place on the baking sheet & flatten slightly with the palm of your hand so that each disk is about 2" in diameter & ¼" high. Place the balls about 1" apart on the baking sheet; they will not spread much.
Bake for about 30min, until golden & crunchy; then transfer to a wire rack. The cookies will crisp further as they cool. Serve at room temperature.
