Notes
Make sure you leave the cookies on the tray until they're cold to firm upNOTE:Many of the biscuit recipes on my blog have been written and tested before I developed my new Perfect Cookie Method for the Thermomix and Food processors. However, even though the above method is not what's in my "Perfect Cookie Making Course", it's been tested in 3 separate bake club sessions by my students, and it works a treat. However, If you've done my course, I suggest you download the recipe template and follow the instructions. That method is much quicker and easier ;-)
