Slightly sweet, slightly licoricey, very nibble-inducing. A grown-up cookie.
Cream the butter and sugar together in a large bowl. Add the fennel seeds, fennel pollen, salt and egg and beat the mixture together.
In another bowl, combine the flour, chickpea flour and baking powder and whisk to combine.
Stirring all the time, add the dry ingredients slowly to the wet. Shape the dough into a log, cover in plastic wrap and refrigerate overnight — this is important, because you need the chickpea flour to incorporate the moisture of the other ingredients. Skip this step and you will have gritty cookies.
The next day, preheat the oven to 375 degrees. Slice off small cylinders of the log, roll them into a ball with your hands (warming the butter), then flatten them into a cylinder again. Squash each cylinder flat with a the bottom of a glass. They should be about 3/8" thick.
Bake until they begin to color on the edges. Remove and cool on a rack. Eat.
