how to make sugar-free shortbread pistachio Cookies

First toast pistachio in the oven for 10 - 12 minutes to accent their sweet flavour, then finely chop them using a sharp knife. Combine them with flours and salt in one bowl.

Cut the butter into small pieces and melt on a low heat until completely melted. Add Amaretto liqueur and grate lemon zest and stir. Pour this mixture into flours and stir first with spatula then with your hands until you get a compact dough. It might be a bit crumbly, but that is fine since you'll shape it into logs.

Divide the dough in half and using your hands, shape each piece into a log that is 4 cm in diameter. Wrap them into cling film and let it cool in the fridge for about 30 minutes.

Now it's time to slice and bake sugar free shortbread pistachio cookies. Take the logs and cut each into 7 - 8 mm thick slices. The dough may crumble and break but this is fine. If this happens, squeeze any broken bits back into the cookies.

Bake the cookies for about 6 - 7 minutes or until slightly brown on the edges. The cookies will be soft but will crisp up as they cool on a wire rack.
