To make your own millet flour, place 250 g millet into mixing bowl and mill 2 min/speed 10. Use as needed.

If you prefer, you can use activated or roasted almonds instead of raw almonds.

If a square pan (9 in. x 9 in.) is unavailable, use a 9 in. x 13 in. pan. The larger pan will yield a thinner shortbread.

Adding lemon juice prevents the sugar from burning or crystallising, without affecting the flavour.
