This is a delicious recipe i messed it up on the first try but after that i enjoyed the cookies with my boyfriend.
To make the cookies different colors: 1) Omit the cinnamon
2) divide the dough into three even parts
3) Do add _a little bit_ of cinamon plus your favorite spices to the first part of the dough.
4) Add a little bit of of lemon peel, or lemon extract and a touch of pure vanilla extract to the second part.
5) Add a few tablespoons of cocoa powder, plus a good jolt of pure vanilla extract to the third part.
Roll out following the recipe as printed and enjoy!
For sugar edging, you could beat an egg white slightly, then use paintbrush to apply around edge, then sprinkle on sugar, or roll edge of cookie around like a wheel in sugar spread out in a ahallow dish. Leave to dry before storing.
