For some reason, Indian corn cookies have been hard to emulate in the past.
Either they were way too detailed and time consuming, or
they didn't appear the way I wanted them to.
Now with fondant embossers, I found a design that I really like....
and it's not too time-consuming.
Believe it or not, I used a tall Easter egg cutter for this design.
But a longer oval will work just fine.
Outline and flood the entire shape in gold glaze.
Allow the icing to dry for at least 3 hours, and then use either one of these embossers to imprint "kernel" marks into the glaze.
There are other brick texture mats that also might work to make these impressions.
Using orange and brown glaze, outline and flood a few random kernel impressions
throughout the cookie.
(see photo below)
Dust dry chocolate luster dust over the kernels to give it a shaded and rustic look.
