In a medium sized bowl, stir together the almond flour, sugar and the lemon zest.
Add in the lightly beaten egg whites and stir with a fork, until well incorporated.
Stir in the amaretto liquor and the almond extract.
The dough should feel soft and somewhat wet but will still hold together very well.
Fit the star tip into your pastry bag and scoop in some of the almond paste dough.
Pipe 2 inch round spirals of dough onto a parchment lined cookie sheet making one full circle and one half circle over the first. (make sure there is no empty space in the centre)
Repeat with the remaining dough.
Place a candied cherry or a whole almond in the centre of the almond cookie, while pressing down slightly.
Bake in a preheated oven at 350 degrees F, for approximately 12 to 15 minutes, till deep golden brown in colour. (take care not to have them darken too much otherwise you'll lose the soft texture)
Warm some honey in the microwave and gently brush the honey over the cookies while still warm.
The honey is optional but it adds such a lovely sheen to the almond biscuits and helps to maintain their softness.
