Thought I should put up the recipe for the Matcha Shortbread Cookies I made. It is my mother's recipe that I modified.
Oven temp 300-325 degrees
1 pound of salted organic butter, good quality
1/2 pound of very fine organic sugar, (approx. 1 cup heaped)
6 C less 2 Tbsp. of organic flour sifted
2 Tbsp. of organic Matcha powder
If you can't find very fine organic sugar, castor sugar is a non-organic substitution or blend organic sugar in food processor with blade or in blender til fine.
Kneed butter & sugar together. I do use a mixer with the paddle for this. Add sifted Matcha powder & flour. Kneed together in mixer til just starts to come together, then finish by hand. Roll or pat flat. Cut into shapes, squares, wedges, etc. Place on an un-greased cookie sheet. Cookies do not rise or spread, so roll & cut accordingly. Prick surface all over with a fork. Bake 20-25 minutes. Sift very fine sugar over the top when hot if desired.
